I recently read about https://murena.com/ which is a degoogled OS. Might be not enough for your needs, but others might find it useful.

Hotaru is firefly in English and this reminds me of one.
So you want to backup or do you want to file share/work together on documents?
For backup I use Spideroak for all our families computers. It did a solid job over the last four Linux laptops and MacBooks I used. I only backup the home directory and the external drive with my Photo Library.
For Cloud Storage I use OneDrive. I don’t have much to share, so this is normally enough.
The term you and @Yote are looking for is enshittification. Cory Doctrorow wrote a blog post about this.
Ok. KSP and its 5 SPF gameplay did lower my expectations to modern games, apparently. Looks like I run BG3 around 15 to 25 FPS 🙃 . This is on the internal display. I didn't test the external one.
2000somethingx1600 is on the internal Display of that MacBook Air and it might be that my expectations to graphics FPS wise are not very high. Normally I play Civilisation or Kerbal Space Program and one of my most loved games is Master of Orion 1 on a whooping 640x480 pixels. I’ll check later, what FPS I get.
I have the same hardware and play everything at ultra at 2000something x 1440 resolution. I did not measure FPS, but it does not stutter and videos are sharp. This is on the internal display. I have to see how it performs on my 4K display. Any good method to measure FPS?
There was a meme in Germany during Chancellor Merkel's time in office. As soon as Merkel "expressed her utmost confidence" in someone, that person resigned shortly afterwards.
