tl;dr: for a rocket it is waaaay more important to go fast than to go high. and earth rotates very slowly, so going higher doesn't make you much faster.

So would it be theoretically easier to launch rockets at the equator since that's where the spin is the fastest?

That’s why rockets are launched from there.

And another fun fact: because it’s spinning, the earth isn’t a sphere. Centrifugal forces make the earth thicker at the equator.

Height is typically specified on sea level but for leaving earth it doesn’t matter, distance from center mass matters. And at the equator you’re already further away than any mountain would ever bring you.
