I have 443 open and don’t have any issues with endless captchas or anything you’ve mentioned.

Not the answer you’re looking for, but can RethinkDNS not run over port 443 to bypass those blocks? I’m not familiar with it at all, but that’s generally how I get around VPN blocks.

Self hosted invidious with trusted-session-generator works for me.

I like Clipious with Invidious

I’ve been using Graphene since the pixel 4a, have never considered going back. It works wonderfully.

Export backups regularly or host your own.
