Perspective/Foreshortening Help

So I recently got out of a long art block and am trying to get back into art. I’ve noticed that I can still draw more or less how I use to but have forgotten a lot of skills and information for how to do said things. Right now I’m a bit confused when it comes to perspective and foreshortening when drawing characters. For example I know that in perspective the closer something is to its vanishing point the smaller it’ll appear, however I’m unsure of what perspective to use when drawing boxes for character. Do I draw them in 2 point perspective or would they theoretically have 3 point applied? Or is Three point perspective only for dynamic posing, crazier angles, and structures that form way up from the horizon? Anything would be helpful
