Confused on Residency Paths

Hello! Looking for any advice regarding residency. Currently I am a P4 halfway through my APPEs. Before starting fourth year, I was really interested in critical care and emergency medicine. Having done some rotations my views have changed and I am now questioning whether or not I should pursue critical care. Some other areas that interest me are internal medicine and transplant. For me I want to retain alot of the knowledge I acquired throughout school and not specialize too much. I like a challenging fast paced environment and like to see something new everyday. Any advice helps!!!
