How to improve security and privacy for fedora ws?

Privacy
1

what else do i need to get as good as possible security and privacy of my pc?

here are the things that i want(if is possible):

  1. minimal local personal data

  2. minimal disk space usage

  3. randomization of all information(log, report, etc.)

  4. maximum performance

btw, i use fedora ws(gnome desktop), if other choice are better pls let me know(except atomic updates that take up very much disk space)
