Fine, I'll refute both of the points that could be used as proof she's from the First Era.

"She didn't know what the Empire is".

I have two reasons for why this may be. Number 1: In the Elder Scrolls Online (the end of the 2nd Era) the Caramoan dynasty was destroyed by an Akaviri invasion I think, could've been something else. Well, never the less their was no Empire at the time, if Serana was born into this time period it would make sense for her not to know that there was an Empire in Cyrodiil. Number 2: She might've lived her whole life without it. Or since she probably lived in Castle Volkihar with her family away from the world she didn't hear about Talos. Do you think Harkon knows about the civil war, or the Dragons returning?

"She was surprised that the Dwemer cities were run down".

She actually said in another comment she didn't even know what the Dwemer looked like, only what she heard. So that could show she only reads her books about what the Dwemer were like as opposed to actually being alive when they were.
