It looks like BSSC has a women's league. Registration opens beginning of March. https://bssc.com/event/wednesday-medford-womens-7v7-soccerapril23

I've never played it, but I played in one of their volleyball leagues, and it felt pretty similar to volo.

Yeah, the T stops around midnight. They've tried twice to extend hours past midnight, but apparently they deemed it not worth the costs.

Biking at night/after rush hour is kind of nice, in my opinion. There are fewer cars on the road. You just need to make sure you have lights so that you are visible to the cars and other people on the road. Cold is also a valid concern, but 1.5 miles is about ~10 minutes of riding, which isn't that bad.
