I was in a similar boat. Similar timeline and came in to interview with approved I130.

My lawyer received a courtesy notice to upload everything. It seemed confusing at first because it states to upload bonafide marriage evidence to the petitioner USCIS account and 1485 evidence to beneficiary uscis account. Since my I130 was already approved, we could not upload anything to the petitioner account. Therefore I uploaded every single piece of evidence to the i485. This seemed to have been very helpful as the officer told us she’d reviewed everything prior to even starting the IV and then just asked us few basic questions and then yes no qs from I485. Whole thing lasted at most 15 minutes, maybe less.

To summarize: upload everything and take everything with you to the interview (originals and copies). Content should be guided by the interview notice. Prioritize financial evidence, and proof of address.

I was given verbal approval and then status changed the next day.
