My answer would be no but also that I don't think Biden is significantly more moderate than many of his rivals in the primary (Buttigieg, Harris, Klobuchar).
I'd consider Biden to lean a little bit more towards the Manchin/Sinema/Kind wing of the party than the party establishment, and will these types of Dems ever get nominated for president again?
Biden is the Democratic establishment. The idea that he's moderate is a product of his flowery rhetoric around unity and his long record in the Senate of voting for stuff liberals don't support today. He's whatever the party wants him to be, and he shifts with the party over time. He has no ideological grounding.
