Every plane is different in some way. I would pick an aircraft and do a bunch of touch-n-go’s. Probably start in something like a C172. The difficult part, unless you’re in VR, is judging distance. Just the nature of looking at something on a flat screen.
You can use the VASI lights (red/white lights) to the side of the runway (if it has any) to judge your glide slope visually. Then aim to touch down @ less than 200fpm.
The approach speed, landing speed, flare, flaps, etc… will be dependant upon aircraft. So do some research for the plane you are using.
