Are there any other rocket launches featuring video (selfie) cameras on the rocket than Falcon 9 and Electron?
Falcon 9 has some 5 camera and Electron has 3 camera

One such launcher would be the good old Soyuz launcher. I think this onboard launch video looks particularly nice.
Given the low cost and weight of video cameras these days, I would expect most launch vehicles to have several. Whether this footage is easily available or not is a different problem.
