I’m so glad I’ve been de-googlifying these past few years. All that’s left is an Adblocked YT and a Gmail account I mostly use to sign up for random shit.
Regarding YouTube, the only real options you have are Peertube (which has little content and a discovery problem) or Odysee (which is fine as long as you don’t look at the comments)
As for E-Mail, due to the recent proton situation the only real option (unless you don’t care about that) is self hosting
I am not fully degoogled by any means (it is really hard when family uses and relies on Google products), but you can always start with your own domain and a private (paid) email service (like fastmail or proton). It's an easy step to take for yourself (but getting everyone you know to start using the new one takes time).
I have a Synology NAS I use for storage, photos, and media. It's easy mode storage l, and comes with a lot of apps you can install to replace ones you might use from Google/apple.
tuta has been great in my experience as long as you only need email. I was actually able to just get my last [email protected] and use addy.io for email forwarding.
The only google I use is youtube. I started out on the internet in the 90s and while I was introduced to google, I found it highly unappealing and I was a yahoo guy until I made duckduckgo my default search. I got a lot of my news from yahoo news at one point.
