There's a lot of back and forth on this question constantly in the community. IMO you should just choose a Linux distro that's beginner friendly with sane defaults. Any of them can game, basically.
- Nobara Linux is made specifically for gaming, you might want to start here.
- ZorinOS is made for people who aren't used to Linux. It's got a great UI and good features. I used to play Elden Ring on it, it's very reliable.
- Pop_OS is another great general distro. Lots of people gaming use this. They're also making their own desktop environment which they'll use here when it's ready.
- Arch Linux only if you know what you're doing. If you don't, avoid an arch linux based distro.
