IIRC, the windows version of this is a setting where you can hit CTRL and it makes a moderately large circle that contracts towards the pointer. It’s been in since at least W7/Vista, possibly XP. I’ve used it on and off for years (especially with 3 27" monitors) because of how easy it is to lose the cursor.
Op, make sure you have 3 wires run to your switches if you get Shellys. I only have 2, so I’m not able to use them until I climb up and attach to the fixture.
