English isn't a gendered language like Spanish or French. The random as fuck gendered words we have are remnants of us stealing other language's words. Actress is stolen from the french atrice. Actor in it's original form applied to both men and women since the 1500s. Actor has been considered gender neutral for quite some time. "-or" isn't a masculine word ending either in English. Otherwise we'd have interrogatress, investigatress, distributress, drivtress, doctress, impersonatress, protestress, spectatress, surveytress, or you'd have to give a machine that makes it so lawns can breathe a gender because it's an aerator..
Well you had Waiter, Waitress, Steward and Stewardess, Widow and Widower. There was a time that many professions were assumed to be Male. Policeman, Fireman. Just throwing that out there. You still have best actress oscar. But I prefer Actor as gender neutral for sure.
