Recently, I really enjoyed the scholomance trilogy by Naomi Novik. Had anti capitalist themes and cool world building. main character can be a little polaraizing though, she can be "b wordy" for lack of a better less misogynistic term coming to mind, I've seen some talk about how much they hated her character and others how much they loved her (I personally loved her)
