I'm not saying that she didn't have any liberal centrist ideas like what you listed, but that doesn't mean she was progressive either. A lot of the policy ideas that were actually good were once on the Republican platform before Reagan.

Don't forget about how popular Bernie was in 2016 before he was forcibly removed from the democratic nomination by the party establishment or how popular Tlaib, AOC, and Omar have been. Don't forget about how down-ballot races in this cycle, while brutal to Democrats, didn't push out many progressives. Progressivism is far more popular than the democratic party is willing to admit or fight on, because the party is owned and controlled by the same class currently oppressing us; the billionaires. If a candidate like Bernie presents a real path, they will force the person out. It's not strictly an issue with the Overton window.

Here's the thing about the choice facing people in the election: it doesn't matter anymore as a matter of the current political reality, because Harris gambled hard on the "good cop, bad cop" aspect of "he's worse" and lost hard. That statement is 110% true, but it's horribly ineffective as we saw in 2016 and again in this election. Islamophobia will absolutely increase, and Trump will fund the genocide until all of Palestine is settled by colonists. But once again, don't forget about how successful Tlaib was in comparison to Harris. We no longer have the opportunity to find out if it would or wouldn't have affected the campaign, but the indication is there that at least 1 swing state would have gone to Harris with an anti-genocide stance.
