For different types of CSAs, depending on what you're focused on, some people get a meat/eggs one at one farm veggies/greens at another and baked/canned goods at another. Most producers have some type of option. I like St Stephen's market on saturdays because it's laid out like a village, parking and access are easy, it's almost all food, and they went to a lot of trouble keeping everyone safe. Booths are still more than 6ft apart.Some local CSAs available there or at the Birdhouse market on Tuesdays: Broadfork Farm, TomTen Farm, Shirefolk Farm, Crumptown Farm, Amy's Organic.

Edit to add another resource: Some of these are listed on St Stephen's weekly market vendors page: https://www.ststephensrva.org/community/farmers-market/market-vendor-list-for-saturday/
