Lots to go on.. but start with the Rod Gervais book
Go by this and you'll be OK. Walls with double drywall + green glue will do you right... take care with ANYTHING ELSE that goes through a wall. Doors, HVAC, electrical... that's the tricky part.
Buy this book and read it. When your done, read it again. When your finally done that, read it a third time.

Studio building is 90% planning and 10% construction.
I recommend Aquinas: A Beginner's Guide by Edward Feser. I found it very informative while at the same time being easy to understand.
Yes. It's Enchiridion by Epictetus, one of the prominent Stoic philosophers.

I’m not sure of the Shakespeare connection to angels & other things, but this book goes into details on John Dee, who was a head advisory to Queen Elizabeth & the man whom coined the term “British Empire”.
For the last 15 years of his life he delved into Angel Magicks and conversing with the ArchAngels. It’s a fascinating subject as he may have been one of the most influential people pushing the British empire into it’s height.
My best advice would be to buy and read this before you move any farther:

Next sketch up your design and post it here after you read everything you can find in the forums that relates to your design.

I can almost guarantee someone has already built your room.
Based off your post I can already tell you’ve missed a few big things.
(Friendly note: stop using the term STC. That standard is no where near thorough enough to mean anything when building a studio. It doesn’t take into account low frequencies and those are the biggest culprits when soundproofing for Recording/Music)
Get a copy of Rod Gervais’ book Build It Like the Pros and you’ll get some fairly detailed explanation of how to design and construct isolated rooms.
Note that it all starts with design criteria — how much iso do you really need?
Because floating a room could mean just the walls (I did this in my basement control room build), the walls and ceiling, or all the above plus the floor. Each level up increases the cost, complexity and difficult of execution significantly.
The book will also explain which details you can’t afford to mess up. Unfortunately many people run headlong into studio projects without having a really solid plan considering all elements of the build, and end up blowing a bunch of money for poor results because they messed up a critical element. Little things like shorting out resilient channel because you screwed into a stud, or failing to seal every crack and seam in your drywall, can really kill the isolation gains you fought to make.
At any rate, it’s a cheap way to learn what you’re getting into.
More elegant but not necessarily better
It covers everything you'll need to know/consider
John Dee was an interesting character in history. He served as advisor to Queen Elizabeth I. He led a relatively normal life until he was around 40 years old, at which point he started to talk to angels. They started "talking" to him and he developed a language and a system of magick based off of their direction. The book John Dee and The Empire of Angels: Enochian Magick and The Occult Roots of the Modern World is a well written book on this colorful character.
Angels are generally regarded as guardians of the gateways of the universe. They are portrayed as beings, but really what they are primordial forces that describe how reality operates.
Yup, it's a big project, even for a fairly basic build. Had to do it so I could record in a basement right next to a fairly active railway.
Your sound proofing is only as good as your weakest point. Don't neglect a really sound proof door (that was the weak point for me) and good ventilation (tricky to get enough air in an still keep quiet, mine had enough air exchange, but did get hot with multiple people inside.)
The Rod Gervais book is a great place to start.
Soundproofing is very different from acoustic treatment. To soundproof, you'll need to insulate the outer wall, build a new wall a few inches away from that wall, insulate that wall and drywall (2 layers better than 1). Make sure to only drywall the inside of the inner wall, so that the gap between the walls are just bare insulation exposed. You'll need to do the same thing with the ceiling, and you'll need to use acoustic sealant in all the corners. This is just the bare bones, you can go much much deeper with soundproofing. After this is complete, the neighbours will be happy, but you'll still need to acoustically treat the new room you built, as it will sound boxy and bad.
This book is a bible of sorts, highly recommend to anyone building a studio
If you're going new build I'd just use sheetrock instead of drywall for the shop. At least the room you're isolating. Here's an excellent book that describes options for soundproofing & new construction
Okay thats fair.; Exact category is often debated.
The less debated fields don't have a replication crisis per se: They have a falsifiability crisis.

This is devastating, but I hope the thought that they also have souls and spirituality may comfort you. If you ever feel like it, please, read Making of a Taoist Wizard, where master Wang Liping describes how even little wild animals have spirits and practice their own form of spirituality. https://www.amazon.com/Opening-Dragon-Gate-Making-Modern/dp/0804831858/ref=sr_1_1?crid=106155HRYNRSG&keywords=making+of+a+Taoist+wizard&qid=1649401687&s=books&sprefix=making+of+a+taoist+wizard%2Cstripbooks-intl-ship%2C185&sr=1-1
In John Dee's records of his contact with the Enochian angels they expressly layout the need for Britain to become a seafaring empire and bring about the apocalypse. Jason Louv wrote a whole book about it https://www.amazon.co.uk/John-Dee-Empire-Angels-Enochian/dp/1620555891 and has gone over it on multiple podcasts. It may also be referenced in Enochian Vision Magick by Lon Milo DuQuette but I can't recall.
More caricaturing of Aquinas, unfortunately. This is not a good engagement with the cosmological arguments. Try something like Prof. Edward Feser's introduction: https://www.goodreads.com/book/show/6963088-aquinas

Foam will do nothing for footsteps (or any sounds getting through from outside the room). You need mass (think heavy dense material) to block sound, and that mass will preferably be decoupled from the source of vibration, and ideally there will be space/air between the source and the mass you have put up.

It will save you a lot of headache and trial and error.
I'd try to determine where the sound is coming from first and foremost although there are things that will universally help... caulk everything (and use backer rod! caulk will crack w/o backer rod), pull electrical outlets and caulk them, pull your trim and put backer rod and caulk around all the floorboards
Most windows are framed like shit when it comes to acoustics so if that's a weak point Rod Gervais's book Build It Like the Pros has a diagram on how to frame a window to reduce sound transmission
And a weak point is almost certainly the drywall. I deal with the same issue and I'm considering ripping my 3/8" drywall out and replacing with 1/2" or even double layers of 1/2" with green glue in the middle
Another common weak point is HVAC. Make sure your vents are sealed from the attic. Sound will find any little crack and travel through
If the whir is actually the air moving through the vent you can make a baffle box. There's also a diagram of how to build a quality one in Rod's book. Plenty of pictures online to give you an idea
The Gearspace forum has many professional acousticians who give free advice and many of them are available for hire as well, I'd recommend asking there. Just follow the sticky on how to format your question you should get some good feedback
If you want to build an actual home studio, read this book: https://www.amazon.com/Home-Recording-Studio-Build-Like/dp/143545717X
​
If you just want to spruce up a mixing station with some better gear and better acoustic treatment, this forum (and a dozen others on the internet) already have LOTS of advice if you just search for it.
​
Good luck!
You want to read this book before making any planning or purchase decisions at all.
Seriously. There are so many issues you haven't even thought of, that will be too late to solve if you jump into it before you understand what it is you're trying to do.
You won't get anything resembling enough knowledge without reading a good book on the subject, and Rob's is the best and easiest to understand. It's written in plain language with minimal math, and if you want to go to the effort of building something usable, you want to go to the trouble of reading this book first.
For a full treatment, I'd point to the work of Edward Feser, whose two most relevant works are his introduction to Aquinas and a book on arguments for the existence of God. I'd like to give an overview, but that would conflict with the point - Feser's thesis is that Aquinas's arguments must be understood in the context of his metaphysics, which would make a short treatment necessarily inadequate, because the conceptual foundations need to be laid first. That said, /r/cosmologicalargument has a few resources written by someone who seems to have spent a good amount of time studying Aquinas.

Just want to comment, that physics dont have to be beautiful minimalistic which is also discussed in the science community and also found its way into popular books like Lost in Math: How Beauty Leads Physics Astray.
Imo it is quite unscientific to rule out solution which are not "mathematically beautiful" or "simple and elegant". Or not searching for solutions which do not meet this criterias.
