A note on “MicroOS on the desktop”: The Gnome variant is called OpenSUSE Aeon and the KDE variant OpenSUSE Kalpa. MicroOS branding is used only for server use due the confusing names. Quoting from https://news.opensuse.org/2023/05/31/microos-desktop-has-new-name/

Simply put? The microOS product namespace is getting crowded. And this is leading to a certain amount of confusion, and causing some support issues. At present, amongst the microOS “family” offered are: Server Products openSUSE MicroOS openSUSE Leap Micro SUSE Linux Enterprise Micro Desktop Products openSUSE MicroOS Desktop GNOME openSUSE MicroOS Desktop Plasma And I think we can all agree, when somebody joins a support forum of some sort, be it Matrix/Telegram/forums/IRC/etc, and says “I’m running microOS and I have a problem” then the inevitable question of “Which MicroOS?” has to be asked. And by their very nature, the Desktop offerings are quite different beasts, than the server offerings, and have quite different support needs. And typing out “openSUSE MicroOS Desktop GNOME” is just too darn long, every time you want to tell somebody what’s running on your machine.
