I can’t offer better advice than @smurfmier1985 about camera settings! I’d bet she knows more about cameras / photography than I do.
Personally, I don’t go too crazy with camera focal lengths. I know from my wife’s photography interest that 50mm, 35mm, and 16mm (I think) are viable realworld camera lenses. So I typically jump between those and see what I like in Blender. Though I usually start out at 60mm as I’ve found to be my preference. I was taught in school that 35mm is equivalent to the human eye..
All that to say: I try to stick to values that have realworld standards but ultimate decide on artistic taste and what achieves my goals (like seeing the whole room vs dof-heavy focus on a particular object).
Very interesting tip from Chris Plush. I’d never considered the 2-point perspective thing for architecture 👌
