I remembered another early one: Housekeeping (1987, Bill Forsyth), which is based on Marilynne Robinson's fantastic book. This just an incredible, sweet, humane, fascinating movie, & broke w/sexist conventions by making the key relationships in the movie, all between women, staying true to the book in this way. Christine Lahti is *amazing*, as is Sara Walker as Ruth.
I Heard the Mermaids Singing (Patricia Rozema) was also that same year. I was a little too young to appreciate it fully.
