I'm replacing an electrical box in my bathroom that connects to both a vanity light and a fan. The idea is to put in a GFCI outlet and a duplex switch for separate light/fan switching.
Right now I'm stuck on grounding:
I have three ground wires coming into the box (line, light, fan). Plus one to ground the box itself, plus one each to the GFCI and the switch. That's 6×12 AWG wires that all need to be connected.
How do I connect that many wires? The largest readily-available wire connector (red) is rated for 4×12 AWG.

First off, you do not need a separate tail to the box itself. Typically we'll wrap one of the grounds around the box grounding screw then on to the splice.
Personally, I use ground crimps. I twist all the grounds at the point I want the crimp, then I leave tails for the number of devices in the box, and cut the rest off right at the crimp spot, then put on the crimp. Now each device has its own tail and the spice is nice and neat and small.
Another option is to use a green wire nut, the one with the hole in the end. Twist, and them cut off all but one long tail and put the wire nut on. This tail will go to one device then on to the next in one continuous piece.
