For how great AMD usually is on Linux, it’s not without it’s issues. RDNA2 (the entire RX 6000 series) still suffers to this day from this 2 years old issue that can cause stutter in games as the GPU constantly downclocks itself aggressively. I still prefer it over Nvidia (having owned one and now using AMD) but just be aware, it’s not all as perfect as some Linux users would have you believe.
Honestly anything with a non LTS release schedule will be fine. So long as you keep a relatively recent kernel and GPU drivers it pretty much doesn’t matter. You can go for a rolling release like Arch or OpenSUSE Tumbleweed or a staged release like Fedora. Even Ubuntu or it’s derivatives are fine so long as you stick to the yearly versions and don’t have a particularly bleeding-edge hardware.
My only advice is stick to the popular stuff. This applies to both distros and desktop environments. Much easier to troubleshoot things and find help and they have more people using them, which usually means the experience is more polished and bugs get fixed faster.
