Pullbacks are indeed easier to define if you view a sheaf as a local homeomorphism. On the other hand, pushforwards are easier to define if you view a sheaf as a set-valued functor.

(Earlier up in the question there are a couple analogies to linear algebra. Matrices are computable whereas linear transformations are basis-free. Both define the same thing so it’s worth being able to think in either of the equivalent viewpoints.)

Have you heard the song secrets by IPS?

Yeah, a couple times before on Youtube from live videos only. It's very surreal and has a lovely tune, and also sounds fairly close to The Waiting Time (Vans Session Acoustic) in my opinion.
