I assume you are aware of the requirement for AFCI protection, even in a detached garage? And if so, the acceptable workaround so you don't need all AFCI plugs?

Service loops: Might as well, it will save potential headaches down the road

Connection to the panel: I had all my wire ends loose in the panel and zip tied together for the rough inspection, they were fine with that setup

Electrical boxes: I stripped the sheathing off and left it sticking out of the box. The boxes that were in the middle of the circuit simply had more wires sticking out, I didn't pigtail them

15A circuits: Ditch them. Just have all the outlets as 20A, no point to have both in a garage

Other things to consider:
- Add some outlets with the USB charging ports integrated. I have them along the wall where my work benches are, makes it super easy to charge phones while having it close by.
- Add an occupancy sensor to your lights, nice to have all the lights come on when you open the door.
- Outlet high up on a wall so you can plug in a TV if you need to at some point.
- More than one outlet on the ceiling, you need one for the garage door opener, but space for drop lights is always nice
- After you are done running everything, take pictures of all the walls. Keep all wiring at uniform heights as well
- Plan where your work areas will be and place lights appropriately, now is the time when you can eliminate shadows over workbenches
