Fedora Kinoite is already on the website.
The rest are specifically not recommended. It doesn’t matter what “infrastructure” runs on, because the recommendations on Desktop/PC - Privacy Guides are for desktop computers which have completely different requirements than servers.
I would recommend reading Linux Overview - Privacy Guides, and if you have additional desktop OS recommendations you can create one new thread in the Tools Suggestions category here for each one, as long as reasons why it should be added instead of just a link to their website.
We might add server operating systems in the future, but that is already being discussed: Does Privacy Guides have a stance on self-hosting?
