I've now finished all 5 main girl arcs, and to me it felt like Josy/Maya was DPC's intended direction, but Sage still felt like the most natural to me.
In terms of rankings, I'd go
1. Sage
2. Maya/Josy
3. Jill
4. Bella
Sage was my first choice and is my "canon" story that I will be playing (I will finish the rest of the stories after), I've loved reading peoples character breakdowns and Sage's flaws definitely resonated with my "I CAN FIX HER" complex that i've struggled with in real life, but also has long term consequences in terms of her finishing college, whether you entertained her mum, how you treated Tybalt etc, which makes me nervous cause I feel like Sage could be the "good ending".
Maya/Josy feels like it's set up for further conflict and the girl in the room with Maya after the halloween party (Melanie?) foreshadows that MC will have to choose (Maya all the way). Jill's story was fine, and Bella's also feels like its set up for failure.
In terms of general story predictions, I feel like Tommy will get ousted from the frat, especially if you're following Maya/Josy's path, Rusty becomes leader and you become vice
Now for the rest of the side characters, I may also re-do my Sage save and try not to get Tybalt and his Mum to hate me this time
