If you end up archiving youtube content, consider stopping by my discord server. https://discord.gg/EJvS4kf

We maintain a list of content that various members have archived, such that when content is removed from youtube, people can direct inquiries to contributors who have archived that content.

It's a small way to keep track of what things have been successfully archived, and direct efforts toward at-risk channels.
