I think I would run the fridge off one of the SA circuits ahead of the GFCI. They really do not pull that much current these days. I have the one outside in the tiki bar on a Kilowatt meter for over a month. (side by side with ice and water in the door) I am really surprised how small the load really is.
I suppose with some planning you could put every outlet that is not required to be AFCI or GFCI on one circuit. There really aren't that many. (if it was my house I would also sneak the smokes on that circuit but that would be wrong
)
I have heard stories about the mythical AFCI/GFCI (Cutler Hammer) but it will just be an AFCI with 5ma GF protection, instead of 30, nothing magical.
