Assuming you are a Linux beginner
picking your first distro, I'd recommend something stable, established, and well-known. Especially since you are asking.
So Debian or Fedora. Maybe OpenSUSE, Mint (Debian/Ubuntu base), vanilla Arch or EndeavourOS (Arch base).
Wouldn't recommend up-and-coming perennial community derivatives depending on a very small number of volunteers like Omarchy to someone who does not yet have the confidence and experience to fork/maintain it themselves. Projects like
Omarchy can be great as inspiration and starting point for your dotfiles once you have your bearings and can judge it yourself but not wise to treat it as a "black box" or set-and-forget the way you can more safely do with a classic distribution.
Then you can of course run either KDE (good choice), Hyprland or whatever other Desktop Environment and Window Manager you desire on your dist of choice.
Or try a few different ones and see what sticks for you.
