To land at a pole, I would think that a s.k. Molniya orbit is preferred for a communications relay satellite. I.e. simply a highly eccentric polar orbit with apoapsis above the surface lander so that it only briefly disappears out of line of sight. The Chinese are using a halo orbit instead, which is great for the far side but not for the poles. But China clearly is the world leader in Moon exploration now. With LOP-G NASA has demonstrated that they don’t have any interest in the Moon whatsoever. NASA’s goal is literally to never ever land on the Moon. They are ashamed of the Apollo project or something.
