I need to find out how thick the ceiling drywalls are so that I can get
the screws of the right size. Does anyone know of a good way to do it?

There are only 3 possible sizes. 3/8, .50, .625.

Buy 1.625"(1 5/8) screws and they will work with whatever you have.

Thanks. Is there any downside to using longer screws than necessary?

Normally no. If someone ran a water line improperly there might be a
problem. But honestly if .25" makes a difference I have never encountered
it.
