In a setting where spacecraft can go faster than light you're worried about the same ships having gravity? Just assume that the same hyperspace physics that allow FTL travel allow artificial manipulation of mass an inertia. And then you can add secondary consequences to the system that require, for example, ships using artificial gravity or inertial compensation to bank and such. Boom, all Star Wars physics tied up with a single bow.

Except the sound, granted. However, the sound makes perfect sense as an in-cockpit generated effect; sensor data on the position and velocity of other spacecraft translated by the onboard computers into sounds humans are trained by life planetside to interpret correctly. So the sound you're hearing is actually heard by the people in the spacecraft even though sound doesn't travel in space.
