I am wiring my upstairs bedrooms at this time.(New Construction)

I have been looking at different ways of designing my circuits. I was hoping to get some thoughts on a few ideas.

The following is what I was planning on doing:

I have 4 bedrooms on my second floor. I have roughly 10 receptacles and four 6" recessed lights in the ceiling.

I was planning on beginng my run at the receptacle next to the light switch. Then run my circuit away from the switch completely around the room until I get back to the switch. I would then run power to the switch from my last receptacle. From the switch, I would run cable to my recesses lights.

I was going to run a seperate circuit for each bedroom using this design.

I am using 12 guage wire throughout the house with the exception of my moke alarms(14-3). I am also using all 20 amp receptacles throughout the house.

Is there any problems wiring the rooms like this? I know that if the breaker faults, beacuse of a receptacle, that I will not have the use of my lights.

Would I be better off combining the lights from 2 bedrooms on a circuit and then combine the receptacles from 2 bedrooms on a seperate circuit?

I have been trying to figure out what is the best way to do this. I have read up on different designs but can't really find any clearcut advice.

Another concern I had was derating. When you have 2 rooms back to back, that share a wall, and you want to run more than one circuit through the studs. Should you drill seperate holes so that you dont "derate" the cable? Or, should you design the runs so that when 2 rooms share a wall you make the receptacles on that wall one circuit? I know that sounds confusing but that is the best way I could describe it. I also read that if you leave some slack in the wire so that they are not tightly bundled(like when using cable ties) you don't have to worry about derating.

Well, thanks for any advice you can give to me.

By the way, when I wrote "I have 4 bedrooms on my second floor. I have roughly 10 receptacles and four 6" recessed lights in the ceiling." I meant that for each individual bedroom.
