ahh I've read wuthering heights, it's an interesting book buut not totally my thing. The characters are very frustrating to read, though that's kinda the point ahah. there's definitely plenty to analyse if it interests you though.
for modern books there's big ones like handmaid's tale, maybe The Help by Kathryn Stockett, uhh Gone Girl could be interesting?
there's some great books to look at for relationships between women! think of stuff like Little Women or Emma maybe.
for treatment of women there's the Scarlet Letter or maybe The Crucible if you're looking at plays as well?
don't forget there's interesting comparisons to be made in contrasting texts as well! so you can look at quite a wide variety of texts.
