Is it accessible to people with electric scooters?

You could get onto the board walk but the overlook and devil's kitchen would not be accessible. There's pretty views from the board walk though.

There is, but not to the overlook

Not that I have noticed so I would say no

Most of the way to the overlook

There is a boardwalk that goes most of the way but, I'm not sure if there is a ramp to the boardwalk

Not really.
