Our new builds, the first run we normally pipe after we install the main is 4 12's, (to a single 1900), which feeds 2 duplexes on 2 GFCI breakers for the first floor, and (if the run follows), we've been known to run a third circuit to the second floor, also on GFCI. We either pull it out during our finishing (once other circuits are in place), or use it as part of a branch.
We've also installed a "temporary power point", basically a 2'x 2' piece of plywood nailed to the studs, with a bunch of 20a receptacles in exterior boxes on it, all wired to GFCI breakers @ the main panel.
We usually box & pipe, pull the wire, tape the boxes, let the finishers in, then install the fixtures / receptacles / switches, and then the breakers.
Keeps "little fingers" outta our panels.
