Fedora Silverblue has been utterly fantastic for me. Only item layered is Opensnitch which is of course also amazing
When I look for new distros to try immutables are highest on my preferred list, Aeon & Kinoite, also very nice, can’t go wrong with any of these IMO

Tuta is great, I like it has its own client, in particular Linux has so few options. Thunderbird is became concerning for me based upon FF underpinning & associated AI moves
That said, I team it with Posteo which is also great, and hard to beat the price
Both bring solid reputation & strong company values & ethics
Tuta works only with its clients
Posteo doesn’t do custom domains
In any case you can try Tuta for free. :)
