Nice Federalist Papers call out. I own a copy.
A key phrase that you did not highlight above is " acts committed by public officials that inflict severe harm on the constitutional order" and I have not seen that here. There are certainly accusations of that in the many posts claiming that Joe Biden helped Hunter Biden in his business dealings in a way that is out of bounds while in elected office. Mitt Romney, having seen more of this than any of us here, does not see evidence supporting that stance. Maybe he is right. Comer and Jordan both keep saying or implying they have the evidence, but they have been saying that so long without producing any of it, that they no longer seem credible to me.
As for the turn this thread took yesterday where potentially impeachable offenses were replaced with arguments for impeachment that were things like, "look at all the illegal immigrants streaming over the border", there is just no way that subjective statement rises anywhere near the level of "sever harm on the constitutional order" even if it turns out to be true.
