The problem is you used Debian which is missing bug fixes for KDE, and is on a frankly ancient 5.27 - I have had nothing but an awesome experience on KDE 6, with both VRR, and HDR, working under Wayland.
Whoops, I was actually using Fedora. I had to go check the kde website, as that is where I got it from and thought it would be weird if they recommended something so out of date.

Unironically, I find Arch easier to use than Debian
With the CLI guided install the barrier to entry is also super low now. The only thing I’m still battling is GPU video acceleration with Firefox.
