You can always add the reverb to the track after the fact. In fact, that is the preferred way. Keep the tracks (all of them) dry and un-effected.

Add the FX as plug ins and feel free to experiment. You can always delete them if you don't like what you have and don't know how to get back to solid ground. Then simply start over by inserting it again.

My rule of thumb on reverb is.... select the kind you want.... dark plate, bright plate, hall, small room etc.... then turn it up during playback until you can hear the reverb...then back it back down until it goes away..... as a rule of thumb, you are now probably set pretty much where it needs to be.

Remember that as you add reverb to busses and master, they will ADD to what you have in a track so it may be necessary to go back to the tracks and turn it down even further, and perhaps to remove it altogether.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
