I ultimately settled on IC 80, with Gaussian 2. This has IDL quality at 60 and pixel samples at 12. There is one spot and one infinite with a 5.0 Shadow Blur Radius, and Shadow Samples are between 90–100 (which is pretty much my standard setting). There is also one wall of the room with ambient.

The hair itself needs a bit of tweaking in the back, as I have a little chunk of hair roots intersecting other hair. But overall, really liking how this turned out.
