NeRF's (and all of photogrammetry's) bread and butter is 3D consistency -- that is, seeing the same object from multiple angles. A 360 degree photo from a fixed position just won't do. As to how to select the best camera angles...I'm not sure. I believe there is research in this area for classical photogrammetry techniques, but I'm not familiar enough to point you to a body of work.
