My assumption is that home can be programed to be 10 to 20 mm from the switch like my 3D printer. When you home it, it travels to the home limit switch then moves to the home position about 10mm away from the switch. If cannot do this then I'll rethink my switches. Perhaps someone with more knowledge about UCCNC can chime in on this.

You still have the issue of hitting the hard limit which should be tied to e stop. I agree though you need to first see how uccnc handles it.
