ran it up on a $5 DigitalOcean VM (1GB, 1 vCPU) and it worked fine
with three connected users; htop suggests it was only using about half
the resources available to it.

Quality was OK, too.

But I was then called into a meeting on Zoom and the quality
difference was significant. (And also about half hour into our 40 min

I have to say I was impressed too, until comparing with Zoom. My own
personal preferences for FOSS won't carry much weight when a lot of
those I want to invite to the meetings have experience of Zoom.

That said, Jitsi is a lot easier to join a meeting (nothing to
install, just click the link).

Agree there. Ubuntu suits me but the lack of docs is an issue. For
example I would like to configure it so that only admin(s) can create
meetings - I don't want my server to be a free-for-all - but looking
for how to do that took me down a virtual rabbit hole (and I ran out
of time before the scheduled Zoom meeting).
