So I have NM and CG with pretty “different” setups. Maybe this will help.
NM has a boxy rando bag and dedicated 700c setup. Really optimized for long road rides and fast commutes. I’m probably going to settle on a 700x32 tire when the updated GP5k comes out.
CG switches between modes based on wheels. 650b for fast rides with some chunkier gravel, underbiking around town and living the fast bike with fat tires lifestyle. 700c fast wheels with 36mm tires for fast group rides where there’s dirt roads too. Aero bars much of the time. Minimal stuff on board.
Important to note that pretty much all the long rides in the Immediate are are going to be almost exclusively pavement. Even the 200k routes with some dirt are mostly paved.
I like the traditional trail of the CG for aerobars, gravel, and similar. I’m trying to really slim down this setup and resist the urge to be over prepared.
I love that I can just toss a bunch of crap into the bag on the NM and go. It probably rides a bit better. It planes.
Not sure if that helps or not.
