Can’t help much but I’m curious to see how this pans out. I’m 90% sure that your amount of noise isn’t normal. Was your bike ever quieter? What parts have you taken apart and put back on before? Like someone above said, make sure the chain isn’t rubbing anything in the derailleur cage. Can we see the derailleur cage from the front, looking back? That’s where the little tab is.

Also make sure that you put the pulleys in the right spots (assuming you’ve looks right though), in the right orientation, with the bolts in the right spots (longer one on top) and torqued decently but not super tight.

B tension (screw that keeps your upper pulley from hitting the cassette) seems fine... but make sure it isn’t wrong.
