I had the same plan as you have, switching when win10 goes EOL. but since Microsoft decided that they would backport stuff like ads in the start menu, i just switched.
I’m a gamer, so i decided to give nobara a shot. it works really fine, and i have found only one game so far that didn’t work. Lutris and heroic launcher is everything you need, i do have the VM but i haven’t spun it up since i finished the configuration :-) a few hours in and i decided that i won’t need my windows partition anymore.
If you have a few hours spare time, give it a spin, you’ll be surprised how good gaming has gotten under linux :-)
I switched to Nobara a few weeks ago and gaming isn’t really an issue. I still have to get Cyberpunk running when heavily modded tho. The Xbox Cloud Gaming app is available through an Electron PWA using Lutris: https://lutris.net/games/xbox-cloud-gaming/
