I have a Stanley Click N Connect that works great. The bottom half pops off and stores all my squadrons with a little room left after wave 2. Those are modular so you can add more of them too. Like $14 on amazon. The top currently holds all my ships and everything else. I haven't bought an ISD or MC80 yet though. I think once I finish Wave 2, I'll need another bottom organizer for cards and things so the top toolbox can just be ships. Not sure how wave 3 will work.
Inside the box, almost everything is in sirwillis boxes. LOVE those things. They only thing I don't box anymore is non named squadrons.
I've slowly drifted towards storing all of my small to medium sized gear in these organizers. Anything that can't fit in these either gets hung up, goes into a large storage bin/brew bucket, or gets stored in the kettle.
That is my solution exactly.

My fleet is similar in size. I have a 3rd expansion tray waiting in anticipation of waves 3, 4, and 5.
I also fit a small plano box in the top of the toolbox to hold tokens, etc.
Been meaning to post some. I'll see what I can do over the weekend, but I'm using this with three more units on the bottom layer. I used a lot of self-adhesive craft-foam on the insides for padding, and thick craft-foam for sub-divisions.
EDIT: any photos I post will be preliminary. I'm in the middle of making some major changes, but the box and the general idea will be the same.
If you want ot spend $45, this one is popular:
But I'd probably just go to Home Depot and grab whatever. If you end up being not liking whatever you get, you can always repurpose it back into a toolbox. :)
This may help too:

What's your actual budget?
I'm using a rifle case. It's big, 43", and I discovered the other night it doesn't fit in the trunk of my Miata, so I can't take passengers on game night. I'm buying and playing both armies so all that space is designed for expansion(s). The technician's case I'm also using was great up until Wave III\IV were announced and I realized I needed more space for more ships. It now handles all non-ship objects, including squadrons.

The Plano Stow N Go series of tackle-boxes are pretty popular. I think the 1374 will fit most large ships in the top part.
This guy used Stanley Click n Connect boxes.. BGG has all sorts of recommendations.^1

If you want a full custom solution, Feldherr and Battlefoam both have custom foam for Star Wars Armada, with Battlefoam offering the ability to custom create your own tray inserts if you only need so many of certain ships\squadrons.

Lots of options, lots of prices. Plano\Stanely is probably your most economical option, and in most cases, you'll also want to source some cheap foam to cut\pluck for safeguarding your fleet while in transit.

Feldherr\Battlefoam are honestly probably the most expensive option, especially for larger fleets, but it's the least amount of work to get it organized.
I believe you're talking about the STST19900! I just got one myself, albeit for the original Zombicide. I ran into the same issue with the tile space.
You can center the tiles on the grooves that jut out for dividers. It depends on how many tiles you have, but I have all of the original seasons/expansions, I and was about 7 tiles away from fitting them all using that method. The space underneath is the perfect height for boxes that minis initially come in to rest, so you can store smaller items ziplocked in there with no issue and add stability to the pile.
I wanted all of my tiles in one place, so I ended up using a Dremel to get rid of those grooves. The space still narrows near the bottom (the indents on either side), but I have just an inch and a half of clearance now. I'm in the process of modifying these to be the right height for storage underneath, but that's certainly not required.
It's been about an hour's worth of work so far to get the tiles in and the majority of that was just cleaning out the plastic I ground off. Just did it last night, so I was excited to see someone else using the same storage!
