All the libs will go back to brunch and sleepwalk for another 4 years. Harris will fail at everything she does and make life worse, especially for Muslims, and the left will be blamed for everything. The right will dig their heels in even more on reaction, yada yada, y'all know how this show goes.
It would just be Obama 2.0 but without the charisma and probably with less competency given how terrible her 2020 campaign was. Which aligns with your description. Liberal status quo, identity politics masking social murder, back to brunch, and ascendant reaction as material conditions continue to proletarianize the public while no left outlets for political organizing can (yet) sufficiently capture the disillusioned.
Things will be pretty similar either way, though. Ds and Rs will trade off and govern the machine in ways that lead to the same conclusions. Libs will go back to brunch under D's but that just means we can't backseat drive them. But that doesn't work very well anyways because we are too few. Our work remains, more or less, the same, and it comes back to organizing fundamentals.
