I think part of the problem is that public ignorance of what impeachment actually entails has led people to think that the House just shows up one day, votes on Articles, and then tosses it to the Senate where the actual laying out of evidence occurs.

No, my child, no. There are hearings in the House that are conducted, sometimes taking weeks or months. They act in many ways like a public grand jury, from the presentation of evidence to the questioning of witnesses. You go through the Articles on the table and you make the case for/against every single one before you hold the vote on whether to impeach.

It was the prolonged and damaging nature of those impeachment hearings, as well as the media’s own digging into the matter, that ultimately doomed Nixon and forced his resignation before the Articles even came to a vote.
