Okay, next season:
Blue Archive: The fandom skews heavily towards het, but I understand the actual source material is mostly cute girl stuff?
Girls Band Cry: Girls doing music, from the same team that gave us Love Live Sunshine. I'd be surprised if it didn't at least have some subtext
Highspeed Étoile: Predominately female cast, with the guys all being middle-aged teacher types
Jellyfish Can't Swim in the Night: All-female. And it looks pretty impressive
THE iDOLM@STER: Shiny Colors: Probably won't have much, but might be shippable
Laid-Back Camp: This is back
Rinkai: Unlikely to be good, but it does have an entirely female cast
The Two Sides of Seiyuu Radio: Well, the manga is tagged Subtext
here
Shuumatsu Train Doko e Iku?: Yet another all-female original series. This one looks like an adventure series, which tend to have higher rates of romantic b-plots than the music series
Whisper Me a Love Song: ...It's a big-deal yuri manga
Lotta original series with primarily-to-entirely female casts
