120Hz - apparently the gaming crowd want it.- Vote on answer

Yes, but panning across a scene could be a bit jarring when viewed on the big screen.

I remembered 18 fps, with a 3-bladed shutter in the projector, giving
54 flashes per second.I see someone else said 16 fps, so I turned to good old Wikipedia, which suggests that Super 8 was 18 fps and Standard 8 was 16 fps. So we were both right!

Cable power yes, but it's also very convenient that an HDMI port can power an HDMI to VGA converter. There are so many old projectors in so many meeting rooms with VGA cables even today. The minimum current to provide through pin 18 is only 55 mA though. Not enough to run a Pi.
