Yes. I'm a near surface geophysicist. So I don't look for oil or minerals but I do try to figure out what's going on underground without digging. Mostly looking for mine or karst voids under new construction.

Short answer: yes
Pretty much all of the imagery options available on ID are orthoimagery, since that just means it's been corrected to remove distortions from camera angle, lens, and topography.
Unfortunately, that doesn't always make them perfectly accurate. The only good way to check if a particular dataset is accurate is to record GPS along a feature identifiable in the imagery and check out the offset.
Usually the best one to use is a more local survey that covers just the city (usually only done for larger cities). Also ones where the area you're tracing has a more "overhead" camera angle (hard to trace when the top of tall buildings are very offset from their base).
I think the RapID editor automatically provides a few additional local imagery sets, depending on where you are working.
Gotcha makes sense now
Just kind of an asshole then I guess
No, and even worse "if you have time to lean, you have time to clean"
