I’ve been pretty happy with Windscribe. They are headquartered in Canada, but they have also proven they don’t keep logs. https://cybersecuritynews.com/court-dismisses-criminal-charges-against-vpn-executive-affirms-no-log-policy/

I have been daily diving /e/ is on an FP4 for almost a year. I’ve encountered a few weird things with calls and texts, but that might have as much to do with my US carrier not playing well with a European phone. As for the OS itself, the only real limitation I’ve come across is that Cash App doesn’t work. PayPal and Venmo are fine, and my local credit union app works great. Sometimes the App lounge hangs, but I’ve also got Aurora store for google play apps and obtainium for FOSS stuff. Other than Cash App, there’s nothing I can’t do with it that I’ve wanted to, even if it takes finding an alternative. I’ve not regretted using it, and it only seems to be improving. It won’t be as polished a UX as stock android, but I have no reservations in recommending it.
I’ve been distro-hopping on a 2018 cheapo Chromebook for about a year. So far, I’ve tried Debian (Bookworm) with XFCE, AntiX, PeppermintOS, and now ARCH with Sway. None of the first three were particularly snappy, but they were all running full desktop environments. With Arch/Sway, I’m running about as light as I can get: no login manager, only 441 packages installed. Web browser is Helium. It’s early yet, but I think it does feel a little faster–most of the time. Helium still takes a few seconds to load, for example.
Running bare Arch is a bit extreme, but I think the real difference probably comes down to using a WM instead of a full DE. Sway is pretty light, and from what I could find, Wayland is supposed to be a little lighter/quicker than X11, but if toy want to go that way, you could use i3. Configuration from scratch can be a bit intimidating, but I looked online for shared dotfiles I liked and customized from there.
Good luck! Hope it goes all and is a fun experiment!
