Actually for the Yamaha P-515 this is incorrect. The P-515 has USB Audio support so when you connect your phone to the keyboard with a USB-B to USB-C cable (or via USB-B to USB-A to USB-C OTG adaptor) you can directly record the audio digitally on your phone. I have a Yamaha P-515 myself and have tested this.
You can also record audio via the Yamaha Smart Pianist app but as far as I can tell you're better off recording the audio via another app because they don't make it easy to export your audio files.
I had to do a quick serach to verify that I used to have this digial piano years ago. It was a workhorse for me.
Yamaha made a wooden stand for the P-155 called the L-140. When I quickly searched for it, I could only find one on eBay that had sold recently.
As for the music stand, I don't know if they are universal but here's one to check out.
Possibly related but I just tried it out using two TS cables and this splitter and I notice some clipping/popping when I play loudly (and the speakers are powerful so definitely not beyond what they can output). Any insight is appreciated here.
Depending on your speakers, you could use a minijack-RCA cable and it should work.
I was doing this this morning, but not with a Macbook. Assuming your Macbook has a standard USB port, what used should work:

I see they sell both USB "A" and USB "C", so choose what fits your Macbook.
This reply made me go back and see your last reply that I missed, so thank you lol.
Yep! I ordered on a Friday night I think, so unfortunately I spent the weekend refreshing my email. Monday it shipped, and said it would be delivered this Friday. I was surprised at the shipping speed, I actually hadn't ordered a stand or a bench yet because I thought I'd have enough time to properly research them lol. But then today I checked it and the shipment was delayed due to hurricane Ida or whatever, so it'll get here next Tuesday.
I did manage to find a stand and order one though. I got this one, which seemed to have quite a bit of satisfied reviews, as well as mentions of using it with an fp-90

This is the stand I have for a Kawai MP7se, it’s extremely stable and pretty adjustable as well
The three pedal interfaces are not standardized. That having been said, you don't really need more than a single pedal for a vast, vast majority of music, and those are always 1/4" plugs.
Some do multiple 1/4" plugs, but even pianos from the same manufacturer may not have the same interface.

I had a PX350 and an iPad Air and I can confirm that's the method to connect the Casio to the iPad. The 350 had USB B connector but the principle is the same, you need the camera adapter and the traditional USB cable.
There are other commercial solutions to connect to the iPad using MIDI over bluetooth.
