I can always throw in Soundjack, which is not FLOSS but freeware. We now
provide Mixing Servers that scale up to 64 Participants (Although only
32 are tested yet), possible at any AWS region (I know a pact with the
devil). Soundjack has no video yet, but it is on the roadmap.
Soundjack is available for Linux, MacOSX and Windoof.

If you want low latency streaming, it always comes with a little hassle
of configuring the computer system the right way. It does not work with
onboard soundcards very well, for example.

 From experience, you should stick to Zoom for this, because it is a lot
of work to get the audio system of any participant to work with any of
the low latency streaming solutions. Don't underestimate this!
That's why we tested only 32 participants so far.
