On the switch side the usual pairing is the 6300M in one of its HPE Smart Rate variants, which give you 1, 2.5 and 5 gig on the access ports plus the PoE budget to actually feed modern APs, and the 6400 with Smart Rate line cards where the closet is a chassis. That's the catalog answer, and yes, those ports carry a real premium over straight gigabit.
The honest sizing take: you probably don't need multigig everywhere. A 2.5G AP negotiates down to 1G happily, and outside of dense 6E or Wi-Fi 7 tri-band cells, most enterprise APs never sustain more than a gig of real traffic anyway. The pattern I see deployed most is Smart Rate only in the closets feeding high-density areas, 1G everywhere else, upgraded closet by closet as refreshes come around. Price the design that way and the quote gets a lot less unbelievable.
