However, considering that FSD now is planned to be superluminal, I don't see how it could not also be used to assume the required velocity to stay in orbit around another body. Here's hoping that the ships will actually settle into their orbits due to proper changes in velocity, not just magically stay there; I am confident that they will do it right, given that FSD is already declared to not be some magical warp drive, but requires time to speed up and slow down.
I suspect when I use the FSD to approach a planet I will end up parked in low orbit with the planet wizzing below me. The real problem here is not the orbital instance as such, but how do I get on the planet? The speeds of 200+ m/s are nowhere near enough to deal with the situation. I honestly have no idea how they are going to deal with planetary takeoffs and landings, and ballistic hops around the planet. I expect to make the London to New York run at the speed of a ballistic missile, and with much the same trajectory.
