Jurgens said that not everything's gonna fit and they're gonna have to trim things, so what will happen is what already happened in current stories: Batman and Catwoman are not married with daughter yet, so they're never married in the Golden Age either.
Also, that marriage only happened once the Earth is separated into two. The one they're talking about right now is the main Earth. We still have a Multiverse as shown in Metal.
I wanna say that for all those questions, Shazam especially, I'm gonna need to wait until the writer themselves start telling their stories, and I actually think it's gonna be fun watching them trying to reconcile everything, but honestly, I think they're just gonna move on and not bother explaining the past as usual, since just like the other explanations, this is just gonna be an excuse for DC to resell old stories.
