There is direction in space. Space is not a formless void there is order and structure to the universe.
The solar system is shaped like a disk. Most planets orbit and revolve to the same axis as the solar system.
When a star trek ship is seen in orbit, like the opening to TOS it is usually shown orbiting with the up of the ship facing the north of the planet, making a left turn with the planet off the port side.
Having a consistent orientation, like up=north would make sense for navigating a solar system. Federation ships in orbit are always shown rotating to face the direction of travel while in orbit. That’s not at all needed to remain in orbit, but having consistent orientation seems important to the federation.
