It’s definitely better of an approximation than Newtonian physics. This paper might help, as it derives the GEM equations from GR and specifically states what simplifying assumptions it uses, which look to be basically “for greater-than-subatomic distances”. And that’s exactly where you care about gravity anyway. (At subatomic distances, the other three forces dominate.)

(At least, they do when the other forces are configured to counter each other.)
