Rogue, Jean, Storm, Invisible Woman, Psylocke. All the premier Marvel women were X-Women or Sue who comes with the F4, which is why they couldn't use them when it came to introducing Marvel's 'Wonder Woman'. Also even if they owned all of those rights back then, they're all team players and not stand alone.
This is why they were literally scrapping the bottom of the barrel and resorted to Captain Marvel who nobody knows nor cares about.
They couldn't use a few of the other "well known" female supers they had like Elektra, She-Hulk or Spider-woman because of their connections to other properties like Hulk, Spider-man or Daredevil, plus Elektra had blown her chance.
They should've gone with Scarlet Witch as soon as they got her, she's easily the most recognizable and famous female Avenger who is also powerful. Wasp could've been another good candidate. Clearly they didn't trust Black Widow would've been interesting enough.
But yeah, without a doubt, the premier Marvel women are all mutants and Sue, the first Marvel lady.
