My guess would be that there is less weight distributed up front. More weight distributed on the rear creates more heat that allows those sinter pads to be in there optimal state. Your solution of organic pads up front and sintered on the rear makes perfect sense to me to deal with the noise you're experiencing.
You could explain a hotter rear brake with excessive dragging which isnt too unlikely but the weight distribution explanation is forgetting about Newton's first law of...

Anyways, obviously this is completely anecdotal but I've had a few experiences now with TRP rotors (and a couple other heavy 2.3mm rotors, to be fair to TRP) not playing nicely with metal pads and glazing in the front. Each time fixed by using lighter 2mm rotors after very carefully testing for contamination
Why would using a metal pad with a thinker rotor make it more prone to glazing?
My thinking was the less intense / hard braking on the front (more feathering) coupled with greater heat absorption of the metal pads & thicker rotor would mess with the compound transfer to the rotor and slow down the natural burn off of the surface of the pads. Then once it glazes it would just make the problem worse. I did swap rotors & pads between the front wheel of ebike & rear of pedal bike last night and will give it a shot. The sintered pads I pulled off the ebike front were indeed very glossy - gave them a quick sanding pass to take the shine off.
I've previously tried putting on a fresh front rotor & (sintered) pads on the ebike and the noise came back after a few rides. Hence my thinking it's compound related.
