Regarding weight: A heavy camera can be a pain to carry around and can also make your wrists start aching after using the camera for a long time. Just make sure that the camera you choose to buy isn't too heavy when combined with the lens you want to use.
Both Sony FX9 and Sony a9 III have the same lens mount; Sony E. This means that lenses with this mount will fit both cameras.

Regarding lens mount: The camera's lens mount determines which type of lenses you can attach to the camera. Popular lens mounts include Canon EF and RF, Nikon Z and F, Sigma L, Micro Four Thirds, and the professional PL mount.

Regarding internal raw recording: The ability to record raw video internally is found in cameras such as Blackmagic models. It takes up more storage space but is also more flexible afterwards. We don't think internal raw video recording is a requirement.
