Since you asked for "the highest ranking woman in TOS" and not "the highest ranking (female) Starfleet officer" Iīd go with the Romulan Commander in Enterprise Incident: she didnīt just command her own ship, but the whole task force.
Good point. I seem to recall some female fans in the 1970s, probably Marshak & Culbreath, complaining in print somewhere that all the really powerful women of TOS were aliens. And the one Earth woman who wanted to be a starship captain was all kinds of wrong for it.
