KDE is a desktop environment, you can install it on almost all distributions and it will look and behave same (yes can use wobly windows and krunner). I do not recommend KDE on Debian12 as its outdated enough that you can’t install themes from kde’s settings anymore.

Personally I recommend Fedora’s KDE Spin, I believe its a distribution that you can install and forget and occasionally check for updates on kde’s software center.

There’s also arch based distros like cachyos or endeavouros with calamares installer that let you choose desktop environment before install.

Fedora KDE spin might be suitable for you.

I really hope more beginner distros switch to kde from GNOME. When I was first getting into linux and did not know about what a DE was, GNOME put me off from fully switching to linux and themeing it was hell with it not playing nice with qt applications, of course as a newbie i did not know what “qt” or “Gtk” was and did not understand at the time why some applications were not following theme.

while kde default is not pretty it can be anything you want it to look like and its easy to customize and plays nice with gtk applications. GNOME IS very customizable that you might even be able to make it into a usable desktop.
