Not really. All joists will be the same whether you are working on a 1st or second floor, so your floor does not have a bunch of different levels. Usually we use 2 x 12 lumber, doubling joists which have walls above them or decreasing the spacing if you are at the limits of the span. example you have a 22' span in a garage with living area above it, you would use 2 x 12 with 12" on center spacing.

Avoid notching near the ends of the joist or in the middle third of the span. Consult building codes and a structural engineer if needed for specific requirements.
