Any practical Linux hardening guides for Fedora - for a typical threat model, who already follows best practice?

For someone with a pretty regular threat model (avoiding mass surveillance, generally just being private), decent terminal ability / understanding of the Linux operating system, and already good knowledge of best practices (not plugging in random USB's, generally avoiding third party repos, constantly updating, strong passwords, etc).
Are there any guides that offer some sort of benefit for this specific situation?
