The average modern American isn't enduring the US immigration process. The first few years of a Green Card through marriage case should be about building a case for a bona fide marriage. That is reality....make the job of USCIS as easy as possible. A SSN, a driver's license/state ID, joint bank accounts (finance co-mingling/use), healthcare documents, documents showing you live together at the same address, etc. are all documents normally generated in a bona fide marriage. That is what USCIS wants to see. It doesn't hurt to ask yourself "how can I strengthen my case" from time to time during the process. Now, more so than ever, strong evidence is a big advantage.
Good luck on your journey.
