It's not going to be the speed of light.
Maybe a third, or a half, or two thirds. This depends on something or other to do with wires, I'm pretty sure, yup.

Yeah, on copper makes a big difference.
The local speed of propagation/light/energy is slower. 66%ish for rough calculations.

You're mostly right. I used to work in Cable TV, We would see up to 80% for very good coaxial cabling
Twisted pair cabling is a bit lower.
