If you really want silence, you're best off with the fanless MBA. Though Apple noted that in non-intense use the MBP should be silent, you can also see from their performance graphs[1] that the M1 is more efficient than the M1 Pro and M1 Max at low power levels. (<12 watts or so, from eyeballing the chart.)
Makes sense when you consider that the M1 has more efficiency cores than the M1 Pro/Max.
I'd actually like to build myself a home NAS/server with only Gracemont cores if we ever see Alder Lake-L available in a mini-ITX form factor. (Was going to try with Jasper Lake, but that seems to have been effectively cancelled with the chip shortage.)
