I jumped to Linux Mint a little over 18 months ago because of the Windows 11 issues. Figured I'd get ahead of the curve, you know?
I'm with you on the use of linux for media servers/home theater setups. I have a 15 year old laptop sitting under my TV right now, connected to another PC via SMB for all of our TV shows and movies. Kodi works so well, it's incredible how I'm able to serve up all our media in our house.
I will disagree with you on gaming, though. I'm playing all the games I've wanted to play, with the exception of two: Teamfight Tactics and I went to check if I could try Highguard, but it too requires kernel level anti-cheat. So that's a nope for me. But if that's the worst I run into, I'm not that bent out of shape. I have plenty of games at my disposal, including older games without issue.
