Adjustment of Status - I-485

Hey my people hope everyone is doing good! So my interview is coming up in two weeks time and I’m very nervous. Has any member on here been married to someone way older or younger than them? I’m 26 and my husband is 54 and our marriage is a Bona Fide one, I knew my husband 2 years before we got married and I am just worried that we’ll be heavily scrutinize during our interview because of the huge age gap. Another thing is we don’t have any proof of joint finances for e.g joint bank account etc. because I didn’t get my ssn before my interview however I’m an authorized user on his credit card, I’m on his car insurance we have pictures but that’s just about it, I’ll also be getting the affidavits one from his daughter and the other from his best friend stating that they know of our relationship and that’s it’s legit. I also do have a bunch of empty packages addressed to me from purchases that I make online to provide that I live at his residence, I’m wondering if anyone on here could give more ideas of evidences we could bring and share interview experience marrying someone way older or younger. Thanks guys
