I found a youtuber that has Starlink and had them run the dslreports bufferbloat test. They received an "A". This suggests that the jitter should be acceptable to most people on Starlink. Note: If running the test on Starlink, select "cable modem" as the Satellite tests on dslreports have not been updated to deal with Starlinks different behavior.
