You can pry my 49" 32:9 monitor from my cold dead hands.
Seriously though glad you found something that works for you. I could see them being difficult for RTS/ARPGs. I've started getting back into racing games because of my 32:9 because being able to use the side mirrors is cool as hell.
I personally do a ton of game streaming to my Steam Deck which is my main driver for using Windows as it works better with NVIDIA Shield + Moonlight, but I highly recommend you give Pop!OS a try. I'm very pro-linux, but for the longest time it just wasn't there for gaming and I didn't recommend it. With Valve going full steam ahead for the Steam Deck, Proton has gotten so good that for 95% of games things just work out of the box without any issue. Wine even has support for Easy Anti Cheat now and more features are coming every week.
