A person standing at the north pole wouldn't be in orbit. They would fall directly down.

(Wouldn't they?)

I think it would also have to be at an equinox. Otherwise the pole would be tilted towards or away from the sun, meaning that it orbits at a slightly different velocity, so you would have some velocity relative to the center of mass.

I concur. Right up until they exhaled and gave themselves a little horizontal velocity.
