Have you checked the hub of the problematic wheel carefully - not the freehub but the rest of it? Wondering if you've got a cracked flange or loose spoke that only gets noisy when there's both weight on the wheel and drive tension on the spokes.
Do you feel any roughness coming through the drivetrain to your feet on the pedals when it's making this noise?
There is a little bit of roughness that I can feel through the pedals when pedaling, yes. Kind of like a gritty/grainy feeling in my feet when applying power through the pedals, yeah. I haven't checked the hub itself in detail, the most detailed I've gotten thus far is taking off the freehub body, ratchets, and endcap, and degreasing/regreasing and reinstalling. To no success. I don't have a bike stand at home, but I can hear the noise when I flip the bike over on the ground and pedal; it just gets louder when I'm actually riding the bike and applying more power to the pedals. I've checked the spoke tension and they all seem fine/wheel is true; I actually had several of the spokes on this wheel replaced a few months ago (one of them broke during a ride, went to LBS to get it replaced, they ended up replacing around 8 spokes or so because some of them were damaged from chain getting jammed in wheel once). Dumb question: how would I check for/notice a cracked flange?
