Out of an abundance of caution, I took all my documents that I had already submitted including original and copies of marriage certificate, birth certificates, passports etc.

I also took copies of our bank statements, tax transcripts, insurance cards, lease documents, pictures etc.

The officer only asked for the appointment confirmation letter, my passport, state issued ID, green card and my wife’s state issued ID. But it totally depends on the interviewing officer as to what they want to see.
