I had the chance to help the Debian video team at MiniDebConf Hamburg last year.
They use voctomix and have written down many informations helpful for such 
events:

https://github.com/voc/voctomix
https://debconf-video-team.pages.debian.net/docs/index.html

These people have some experience recording sessions so it will not harm to
contact them. For example they 3D-printed a cover to the microphones so they 
can't
be turned off erroneously.

I think the software is comparable to OBS but I never used OBS so can't say for 
sure.

Yes, this will be valid for all solutions!

And keeping audio and video in sync.

Second this. You need to act in real-time and have to know your stuff!

Yes, are they holding meetings online right now?
OBS or something like that will be needed also when real live meetings are held 
up.
