Yello!
so... just to clarify - first and foremost interest is in aesthetics. originally our 2row T32 came with following brakes:
front - 296mm rotors, single piston floating caliper with 60mm piston, mounting hole distance center-to-center (haven't properly checked it) is ~140mm.
rear - 292mm rotors, 172mm parking brake, single piston floating caliper with 38mm piston, mounting hole distance center to center is 122mm.
simplest upgrade is:
front - 320mm rotors 40206-4CU0B, double piston floating caliper with 2x60mm piston. this is factory setup for T32 3ROW and hybrids(may be hybrids were only X-trails?). caliper should be easy to find. right caliper 41001-4CU0A, left caliper 41011-4CU0A.
rear - 308mm rotors (from many infiniti models - original Nissan/Infiniti part number is 43206EG000.) remember to check for parking brake, because there are two possibilities 172mm and 190mm... single piston floating caliper with 43mm piston (right caliper - 44001-1AA0A, left caliper - 44011-1AA0A).
most probably - for mere mortals - this will require master brake cylinder upgrade, for others - this should make your brakes more predictable.
I don't wrote out larger rotors and proper fixed calipers (330, 350mm, 4pots from infiniti etc).
but I do have question - are there budget (but still good) rotor manufacturers models which have these 320 and 308mm rotors slotted?
ebc has nice two options for slotted

though I can't wrap my head around how these slotting thingies make rotor almost 2x the price from "normal" blank rotor:

p.s. all numbers are "on paper" (FSM, rockauto.com etc) - so, until when I will have parts in my hands and will measure myself - not sure, because some of my research said that 320mm caliper has 2x44mm piston, not 2x60mm, but FSM should be correct... single piston calipers piston is 41121-4BT0A. on double piston caliper - piston is 41121-4CU0A... so.. seems that FSM might be wrong.
