I use https://github.com/houmain/keymapper https://github.com/houmain/keymapper to achieve the same thing, Meta + W: open or switch through existing Firefox windows, Meta + Z: open or switch through existing Terminal Windows, etc. It works on Wayland from my understanding, but I'm using X11 as my daily driver.
