Sense8 on Netflix has an absolutely adorable canon f/f couple. One Day At A Time has a cute romance in it, too. Jane the Virgin has two f/f couples, and one of them gets a lot of focus in season 4, but for the most part the focus is on the many, many het relationships, so that might not be your thing.
On Hulu, Runaways has a cute f/f couple, Faking It has a bisexual main character and most of the story is about her figuring out her sexuality (I've only seen part of the show, she doesn't have a female love interest who reciprocates as of where I am in the show but I know she's going to get one). I've only seen a couple episodes of Black Sails and The Bold Type but there's definitely canon f/f couples, I can't give you any information about their prominence or the f/f to het ratio but I've heard good things about the ships in both shows.
