If you care about VRR or HDR, you need a distro with KDE Plasma and use a Wayland session. Plus, you’ll need the latest drivers, so… a rolling release.
Arch based like Manjaro, or OpenSUSE.
If you don’t like that, or you have an NVIDIA GPU then I suggest you try Nobara, made by Glorious Eggroll, big contributor to Proton (Valve’s fork of Wine, what makes Windows games run on Linux).
