I wont reply point by point because others have already done a fantastic job at that.
Install virtualbox, get some linux images from mint, bazzite or what ever other distro you might want or was recomended and install them as VMs in windows.
Set up a list of things in 3 tiers:
- must have functionalities/workflows (crucial functionality)
- nice to have (important to have)
- optional (can live without)
Then in the installed VMs, test out this list, something like "can I change the volume per app, can I change the audio device per app" or what ever is important to you, according to your list.
This way you can test out if its for you or not, you wouldn't even have to leave windows for it.
One thing regarding gaming, as I game quite a bit too - games with intrusive anticheats dont work, most of everything else works with steam proton. Check potondb.com for your games, you will see what works and what not.
