Flameshot is my favorite tool. Has many more functionalities than most and they are quite nice.
I use xorg with i3, but I've used it on gnome and KDE, so surely it works with Wayland.

I don't use KDE however I've used Flameshot for a couple of years now
and it's always worked flawlessly in GNOME under Wayland and Xorg.
