For anyone interested, I did some testing. Both were with the PBP on and mostly discharged, logged in to the desktop, and with the CPU moderately loaded via a muted YouTube video playing in Firefox.

Charging via barrel jack = audible high pitched coil whine.
Charging via USB-C = completely inaudible coil whine.

Not sure why the difference. Something to do with USB-C PD? ¯\_(ツ)_/¯
