Pretty much any Linux distro will work for gaming. Some just do more work for you at the beginning. Linux mint, Pop OS, Endeavor, manjaro, etc, you can game on basically any of them. After familiarizing myself I eventually swapped to Arch, but if any of the other distros I mentioned work, and you feel satisfied with it, then stick with it. Its about finding a distro you enjoy and can work around despite it’s flaws.
I moved on to jellyfin after I found out the hard way Plex servers need to authenticate for use. I’m sure by now there are ways to set up offline authentication but I already didn’t like the idea of paying monthly to stream my own content from my own machine. It just didn’t make sence to me. Jellyfin isn’t perfect, or as flashy as Plex, but it works, looks fine, and its free, not counting a much deserved donation to the devs .
Man, my Jellyfin subscription just rose in price too.
