For YouTube, it's probably not possible to not use its content, but you can try alternate front ends like Piped (and its wonderful Android client, LibreTube, if you're on Android.)
For Gmail, not sure if this works for you but I set the vacation feature to reply to every email I receive notifying them of my new email. I switched to Vivaldi Webmail (Proton doesn't let you use 3rd party clients w/o a subscription plan btw, I'd switched to Vivaldi first so not a major thing for me) but Skiff (paid) looks good, Kagi Search is planning an email service, Tutanota has an email service, and I guess you could self host. While you transition, use a client that lets you have a unified inbox (K9 works on Android) and just have both logged in.
The only thing i have done so far is use imap into thunderbird…. All this is valuable. I want to use a self hosted solution but at the moment its all a surface level thought. Thanks a lot for this comment!!
Proton is in the process of removing their PC bridge in favor of a custom app. After they're done you won't be able to migrate your email away from their service anymore.
Which is ironic, when people are trying to flee from Google. Out of the fire and into the frying pan...
It's in restricted beta currently, only available to a small category of users, and still lacking features. They say it will launch early 2024 but it looks more like mid-year to me (at best).
Point is, it won't happen very soon, but it will happen

This is a show stopper for me on any of the big name 'encrypted' platforms, Proton, Tuta et al - impossible to import/export data. Moving from one silo'ed walled garden to another arguably worse one is anathema.
The thing that sucks the least for me is to pay to host my own email/contacts/calendar/storage via open source apps in a privacy friendly jurisdiction e.g. Hetzner
mailbox.org might be worth checking out, they're a German company trying to offer a comprehensive package - mail, calendar, some storage, some collaborative tools etc.
