And omg, if you need to go with a feminine honorific and you don’t know whether the person is married, go with Ms, not Mrs. or Miss.
I understand what you mean here, except on the difference between Ms and Miss, do you mean this more in terms of writing than speaking? I ask only because I don’t know that I’ve ever been able to hear a particular difference between Ms and Miss when spoken, but that may be more related to my hearing or something that I’ve not realized.
Edit:
Reading a little further, I see that it comes across as sorta creepy? I’d always parsed it as a more informal address compared to the more formal ma’am for femme folks, so this is interesting, to say the least! I suppose it reads sorta like someone calling an adult man, “young man” or “boy” despite their age, since I don’t think there’s something similar to miss for masculine folks.
That would come across creepy, unless from older folks and heavily dependent on context.
