I'm using filen.io. E2ee and zero knowledge service from Germany. Their desktop client just works.
I only use LibreWolf on my pc's and IronFox or Vanadium on my phone. All except Vanadium have uBlock Origin with all social media blocked. I also use Mullvad vpn with social media blocking at dns level. In addition where vpn is not configured I use Mullvad's dns with all content blocking enabled. Of course no Meta or another social media apps on my Graphene OS phone (except Mastodon and Lemmy). As a cherry on top I use a Linux based OS (OpenSuse Tumbleweed) on my computers primarily (some Windows usage for some gaming).
If you have apps that require play services you can install them to another profile in GOS. Profiles stay active if you like and you can get notifications from other profiles as well. That way you can limit data exposure for play services and apps using them. I do this on my GOS and it works very nice. Though you should use Aurora store to get play store apps (you can get it from f-droid). Many apps from play store work well with out play services.
Been using fastmail for over 10 years and it's fantastic. Two thing you should be aware though: 1st Australia is part of the five eyes, 2nd they have their servers (last I checked) in new york.

SUSE Linux Enterprise isn't really a fork. OpenSuse Leap is to SLE a bit like Fedora is to Red Hat i.e. the community version which is then frozen at some point to build SLE.
So my TLDR, is that its possible to be a USER without touching the terminal, but I dont think its possible to be an administrator without.
Suse with Yast makes it possible to administer just with GUI. Not 100% sure if it can do absolutely everything possible but it has lots of tools.
This research isn't peer reviewed so I wouldn't take it at face value just yet.
Not getting updates doesn't make any app inherently bad. Possible bugs just won't get fixed. If an app is feature complete and everything works as they should there's no need to update it.
Are these available on f-droid already?
How? Fahrenheit scale is totally incomprehensible. Celsius at least is using a rational point for 0 (=where water freezes) and same scale as Kelvin.
