Personally I would stick with Biden, but the important thing is that a decision needs to be taken quickly so the Democrat omelette can focus its energy and firepower on telling how Trump is a decrepit 70yo felon, and so on.
The key to beating Trump isn’t the “perfect” candidate, it’s to hammer again and again and again what an utterly shit candidate Trump is, how his first term dragged everyone down except billionaires and how things are worse even now because of Republican lies and bad faith.
