Runbox and Proton for email, Nextcloud and Immich for photos.

Regarding photo storage, Immich is pretty close to a perfect clone/replacement for Google Fotos in my opinion.

if photo syncing to desktop is an option, try syncthing. I’ve got it set up to work only on my LAN, so when I get home it gets synced automagically. also nextcloud.

Skiff (https://skiff.com/) with custom domain for e-mail. Alternatives: Tutanota (https://tutanota.com/) or Proton Mail (https://proton.me/)

Ente Photos (https://ente.io/) for photo storage. Alternatives: Stingle Photos (https://stingle.org/) or Cryptee (https://crypt.ee/)

It looks like ente.io for photo management will probably be listed on the privacy guides website soon: https://discuss.privacyguides.net/t/ente-photo-management/11763

For email/calendar/drive Proton is the easy choice. I know photo upload is on their radar too but like everything with proton it will probably be a while before that’s ready to roll out.

Luckycloud is working on integrating FolderSync into their mobile app so you’ll be able to do two-way photo and file sync (ie. Delete from your computer deletes it on the phone if you want.)

You can Google takeout your subscriptions to a json file you can then import to alternate front ends like newpipe.

you should check out freetube

You can go to your Google settings, do a Google takeout with Youtube and YouTube Music, which lets you export a file with all your subscriptions. This file gets sent to your Gmail inbox. Invidious, Newpipe, Piped, etc., they all support this file format. Import and enjoy. Hope that frees you from Youtube.

I moved to my own instance of Piped and haven’t looked back. Interestingly, I find that the whole platform have become less addicting as a result.

You can follow your favorite youtubers using RSS. The format for it is https://www.youtube.com/feeds/videos.xml?channel_id=<channel-id>

Honestly?
