Here you can find reviewed, impressive and comprehensive European alternatives for digital products and apps if you wanna break from American (big) tech companies.
Have a look, you'll be impressed...
That's kinda my point, though. The solutions I mentioned in my original comment are already approaching the same level of simplicity as a smartphone, and they should be recommended over centralized options as much as possible. I'm not suggesting that the average person should try and host their own email, but with something like Yunohost, running a copy of Nextcloud or Seafile is about as difficult as installing their corresponding apps on your phone.
