not sure If I understood what you mean but the closer the more accurate

Too close and it will mimic short focal length (selfies), too far and it will mimic large focal lengths.

Best and more realistic would be at talking distance, i.e. imagine talking to someone face to face. That distance. It would have a balanced amount of focal length.
