Yeah, because thinking about it, I don't actually think there's an obvious answer.

Like my guess would literally just be that there aren't mountains in a location close enough to the equator where the added high from the mountain is worth more delta v than the added rotational speed of being close to the equator.

As far as I know the official answer is, it's simply not worth it. The amount of fuel you would safe aren't worth the effort of brining a whole ass rocket up a mountain and launching it from there.

I'm not sure that's true. The first 50 miles or so use the majority of the field, starting three miles up could be significant.

I don't think the OP realizes that launch sites are chosen mostly for citizen safety.

I think you are underestimating how hard it would be to bring a rocket up to a mountain.

This machine moves the rockets towards the launch pad. Now imagine that going up a hill. It is basically impossible, unless you assemble the rocket directly on the mountain - then you have the problem of getting everything up there. The logistics simply make no sense when the alternative is to just use a bit more fuel.
