Yes, it’s depressing but I don’t know why you say that after writing Michelle. She’d be awesome but I doubt she’ll run. 
Otherwise, in no particular order, there’s Warnock, Newsom and half of those who ran in 2020.
There’s lots of smart democrats who I would love to see as President.  Tammy Duckworth. Katie Porter.  Adam Schiff (which Reddit refused to allow me to spell correctly for 4 tries). >

A reasonable moderate would be good from either party for the country but I don’t see that happening. My bets for the outcome are Desantis vs Newsome. >

This isn't a perfect replacement IMO, but
PAUL RYAN VS STACEY ABRAMS 
YOU HEARD IT HERE FOLKS >

Ron Desantis ,  Nicki Haley 
On the left ……
Michelle Obama, maybe Buttigieg
I’m depressed writing this out, our country is fucked
