>Check your local code for smoke/co2 detectors, arcfault circuit breakers and make sure to have neutrals in the switch locations.

In addition to the mentioned reasons to check code, you'll want to see code on how often to staple the wire, how much slack to leave, when to use pigtails in boxes (probably always!).

Also, whenever I'm doing significant reno work in a room and rewiring it, I try to put lighting and receptacles on different circuits. I'll do the lights first, and then I have nice bright overhead lights to work under when doing all the rest of the electrical.
Lastly; this is personal preference, but I like to use dimmable can lights with a non-lit fan because I'm tall and always duck under the fan even if I don't have to.
