Entirely just sounds like tire noise to me. But I'm not able to diagnose it physically

In that video the frequency is tied to vehicle speed rather than engine speed (if you watch the tach). And based on the replies in the video, the guy thinks his aftermarket big brake kit introduced it, and switching from race pads back to street ones reduced it 90%.

The fact that yours does it in or out of gear would also suggest it's nothing in the powertrain upstream of the transfer case. And you say you just did brakes in December. So I guess the next two things to try are re-bedding the brakes (a good handful of aggressive rounds of braking to get some heat into the pads and scrape any rotor deposits clean), and doing the driver's side wheel bearing, which will hopefully be quick since you just did the other side.

another update.

replaced both the driver and passenger wheel bearing, re-bedded the brakes, and the noise is still there

at this point I'm thinking there is something wrong the front differential
