First FPV Drone build - fpv camera system recommendations

Hey, I'm thinking of building my first FPV drone. I'm going to be flying both indoors and outdoors, so I'm thinking of building a Cinewhoop. I need recommendations on what fpv camera I should get, with the requirements being at least 4k 60fps (or 120fps if possible), or if I should just get an analog camera with an action cam mounted on top.
