Oooh, like fictional books are fine! I was stick on non-fiction, sorry.
I wonder how you might like The Remarkable Retirement of Edna Fisher. It explores really a couple of different things with a focus on the main protagonist as an old woman and her place in society and how she's viewed by others. It also touches on dealing with things like anxiety and PTSD. It's fantasy, about an elderly woman who is marked as the Chosen One to defeat an army of dragons and how no one believes in her. I'd say for a teen to young adult audience.
30 to 50 Feral Hogs is about a woman who defies really all societal expectations of women. She's muscular, queer, loves to fight, non-feminine. It's about how she carved out a place for herself in the world and that all came crashing down on her, so now she's hiding out in a tiny little town hiding from her own shame.
I'm not sure how you'd feel about the Paper Girls trilogy. It's a YA fantasy that explores the impacts and devastation of sexual assault and how wrapped up in oppression it is. But it deals a lot with societal expectations of women and the damage it does to them.
There is a prominent romantic relationship (polyamorous) in Iron Widow, but I still really want to suggest it. The protag is technically nonbinary but that's not a concept that really exists in the world (set in a fantastical/sci-fi influenced historical China), so she presents and is treated as a woman at least through the entire first book. But it's got a ton of themes about misogyny and class that are more central to the plot than the romance.
I have the book sitting on my shelf but have only watched the movie, but I feel like The Secret Life of Bees might be a fitting book here. It's about a lot of women who've carved a niche out for themselves kinda off in their own little world taking in a child of abuse who's trying to come to terms with her past and figure out who she is. It's a lot about finding your place in the greater world.
The Lady's Guide to Petticoats and Piracy has an aroace protagonist and def heavily explores themes of intersectional feminism, so might be good.
I may be reaching with some of these. I'll keep thinking.
