LineageOS isn't similar as it isn't a privacy/security focused OS.

Recommend https://eylenburg.github.io/android_comparison.htm which is a third party comparison between different alternate mobile operating systems. It could include many more privacy/security features but it's a good starting point.

OR

https://privsec.dev/posts/android/choosing-your-android-based-operating-system/ is an article with more long form comparisons between OSes. 

 Good point 🤘
