Ellen Ripley’s gender doesn’t matter until Resurrection, which isn’t the highlight of the movie.

A lot of media have strong female characters but their gender or sex does matter for the story so can’t easily be replaced

Susan in the book Soul Music (plus some others) as well as the Witches, Tiffany Achings and more from Pratchett

Death from Sandman (even though the author is very controversial, but you could check the books out from sources that doesn’t give him a kick back)

Was a long time since I read them but the Polgara books feature a strong female protagonist

We got classic youth/kids media that shows strong female characters even if some stuff are coloured by weird takes (Such as Xander Harris): Xena, Buffy and Pippi Longstockings
