The camera system is the main technical failing in BG3 as a videogame. It's not awful, but given the beauty of the environment, and the verticality and complexity of the settings, the inability of the camera system to offer 1st/3rd viewpoints ( my main gripe ) or fully encompassing viewpoints is disappointing.
I have not tried it myself, because I prefer more intimate cameras in RPGs, but there is supposedly a tactical camera, which might help you ( activate by the "o" key, I think, but you can check the key bindings in the options menu )
The tactical camera doesn't solve all problems. Quite often, there are enemies high up in some rafters/lookout tower/mesa which the camera doesn't quite give you the ability to see. Even the tactical camera saw fit to zoom itself to the elevation which made sense only relative to the lowest level.
