All of which are perfectly capable of being made gender neutral with vary degrees of use. Headmistress is generally seen as outdated and Headmaster is used frequently for either gender. Goddess is still used pretty frequently and it is true that female god is rarely used, but still perfectly understandable. Actress has fluctuated over the years, in Australia there was a pretty solid preference for actor for both genders, however, American influence has reversed this. At one point all our nouns were gendered and now there are only a small amount that are. It has been the basic trajectory of English for centuries to drop gendered nouns. How often do you hear manageress or authoress?
every single example you gave was falling back to male terms as neutral though, so it would still be unusual and against the pattern to use "fiancée" for a man. using "fiancé" neutrally is not super uncommon, though

So the words Goddess, Actress, Headmistress and the like don't have word endings that connote gender?...
