Try Flameshot on X11 or on Wayland, and see for yourself. It simply works. Wayland has some rough edges that we are working on, but it works. Give it a try. We support Gnome, Plasma, Cosmic, Sway, Niri, River, Hyprland,... and labwc is wlroot-based, so it works.
To capture a monitor, use `flameshot screen --number 1`, to capture part of a monitor interactively, run `flameshot gui`, or part of a screen automatically, run `flameshot gui --region 100x100x100+100`.
