Thanks, there is actually some packaging work to get that tried and tested network into debian to be seen at: https://salsa.debian.org/debian/hubzilla
And there seems to be another free “cloud” web frontend, similar to hubzilla, but based on the classic XMMP network. Still adding public publishing (blog/news), timelines, and video chats (compatible to recent conversations.im), and it’s already in debian: https://movim.eu/
Movim would also seems a good fit for XMPP on the freedombox (where hardware performance allows for actual publishing and not just the server and a JSXC webclient), but is lacking those hubzilla features that came with its years of experience.
Added:
A look at these hub/pod software projects showing their own public dev blog channels:

https://zotlabs.org/channel/hubzilla
There seems to be some overlap with the Nextcloud thread (Status NextCloud as App?) and its features concerning internal drive filebrowsing, but I’m not sure how far this goes.
And it’s the same with the new pydio cells web interface posted there.
Hubzilla, without the current unfinished packaging state of these two, seems to be a typical PHP website installation (also possible on a freedombox: Installing and containing custom applications/software).
