Based on everything you've said and done it sounds like you're going to need to be underneath with a stethoscope to figure it out. As others have mentioned, once the vehicle is off the ground it makes diagnosis of wheel bearings more difficult using just your ears. There's no load on any of the spinny bits so noise is much more quite if audible at all.

Either bring to shop for diag or return vehicle to service and wait for noise to get louder so it's easier to tell where it's coming from.

That's all I've got. Good Luck.

So, finally an update! Since the last time I posted, the sound had gotten a little louder. I was pretty confident it was a wheel bearing, but still not 100% sure it was the left front one (probably 75% sure). I was able to order a pair of slightly used OEM ones (13k miles on them) cheaper than a single aftermarket one, so I did. Well, fast forward to today. I finally had the chance to work on my car so I swapped out both hubs. Took the car for a drive and the sound is gone! The left hub was making a slight grinding noise, so that was the culprit. Needless to say I’m now happy again. Next up, E85 kit��
