For context I’m 5ft 7in with a 30in inseam, and I ride a 49cm Parallax with a fairly racey fit. All depends on how aggressive you want it to be. Photo attached for sizing reference (excuse non drive side!).
My other road bike is a 53cm Salsa Caseroll which is super-chill and fits comfortably in a much more relaxed fit.
