I don't know why you need ssh with Xorg on your phone though? There are ways like scrcpy to control your phone remotely. Apps like KDE Connect on Android already give quite a bit remote control opportunities too. There are open source remoting apps that fit the Android user interface better like RustDesk. If you still want an Xorg running, there is nothing stopping you from encapsulating it in an Android app too.

For example to run gufw on the Phone, but access it on my computer? Sure I could also learn to do it in the shell, but it is so damn convenient. Sometimes it's also nice to run an editor directly on the device itself and not run the editor locally on an ssh-mount.
