Context I replaced passenger side wheel bearings myself and had a shop do the other side’s due to time constraints. There is a low relatively faint grinding noise occurring at low acceleration but seems to go away above 30 mph. It Preexisted the wheel bearing replacement, but being a novice perhaps the bearing I did not do something correct in the r/r. Or perhaps it is another issue like breaks etc I should look into. Does anyone have some diagnostic advice?

Shoot, best I could say is you might have to get the tires in the air and rotate them to try and diagnose. It may not necessarily go away at 30mph it might just be harder to hear.
Does the noise change when turning the vehicle? Does it change when applying the brake? Does anything you do have any effect on the noise ?

Seems like applying the brakes do not cause the sound. Only thing I do that effects seems (from what I can hear, you are right it could just get drowned out at higher speeds) to be the rate of acceleration… I do not notice anything with that sound while turning.
I'm just taking a guess here based on not much but I'd say it does relate to your bearings but I'm not experienced enough in there to know what it could be. You mentioned the noise was there before the bearing job, which sort of throws off my theory.
But generally speaking, if it doesn't change when applying the brakes and it doesn't change when turning then I'd guess it has to be related to just rotational parts like wheel hub, axle, etc.
I suspect you will eventually need to get it on a lift and spin the tires to see if you can recreate it
