I recommend using Kiwix, https://kiwix.org/en/

They already have a monthly archive of ifixit available: https://library.kiwix.org/viewer#ifixit_en_all_2023-10/home/home

There are tons of other offline resources available for Kiwix as well https://library.kiwix.org/#lang=eng

If you want the security/privacy of whonix capabilities with the flexibility of fedora you should checkout Qubes OS. As long as you have the correct hardware to run Qubes it can make for a secure and unique experience.
