they become negligible pretty quickly when you get into and then leave orbits.

You're not wrong, but it's worth noting that in low earth orbit (e.g. typical ISS orbiting altitude) earth's gravity is still 90% as strong as at sea level. Astronauts on the ISS are weightless not because they escaped earth's gravity, but because they're continuously falling.
