Thank you, all.
I doubt it's really necessary, but I always use the same fluids the car came with. Different companies use different additives and since nobody will reveal the additives they use, I stick to the Nissan branded fluids. Far as heat during braking, I live in one of the flattest states in the union so no long downhills. That leaves the lovely stop-n-go, choked surface roads. I chucked the factory rotors years ago for Brakemotive brand slotted / drilled rotors. They are much higher quality, with a beefier design, and less expensive since they don't have the mandatory Infiniti 50%^ markup in the price. When it's time for a brake job, I get a complete 4-wheel set of rotors, pads, and incidental parts for less than the cost of a single axle 'pads-only' job at the dealer so I get new rotors every two years. This is the second M, 4th set, and 7th year using Brakemotive without a single squeek or warp. They get chucked and replaced when the dealer reports the pads at '3' during my oil/filter change inspection.
