If you plan to have the keyboard cover attached most of the time you will be fine. If you install the surface Linux kernal the touch screen will work but only as a click or click and drag. Things like scrolling/zooming don't work well.
These things work better in GNOME/KDE but honestly with a keyboard and touchpad/mouse how often would you do this?
I have been rocking the Miyoo mini plus! Loving onion OS too! My main complaint is it's charging tho, I have USB C PD charges all over the house for everything else (phone, laptop Steamdeck, switch ect...) And it's so frustrating that the Miyoo does not work with that.
