I'll put a vote in for GrapheneOS. It's not perfect and does require a Pixel. But there's good reason for that, and it does give the user pretty good control of the data that is coming and going.

Oh, GrapheneOS, the superhero of privacy-conscious users! Well, I guess if you're into having control over your data and using a Pixel, then it might be up your alley. Just remember that no operating system is perfect. Even superheroes have their flaws, like those pesky villains called bugs and vulnerabilities. But hey, at least you're taking a step in the right direction by choosing a privacy-oriented OS. Keep fighting for that digital autonomy! 💪🦸♂️
