First of all, congrats on that job, dude! This is what I get for never reading pubski and being too issue-focused. Sorry, I remember hearing about your prep for this, aaaaaaand of course you nailed it. :)
I remember this terrible bootleg, which we used for Halo, it would simply assign one Xbox as "host", and then the worse the host's internet connection, the more advantage they had. Cool, fun times (NSFW, and damn! 13 years ago. checks out with the 2006 tag on the XBconnect git file).
You're right about the default UX needing to be simple, and I'm sure the package deal as well, probably something like calendar software that integrates easily with company e-mail servers. The opposite direction most companies seem to be moving right now, in my experience. Zoom is still OK. Or, no, but it's best, imho. The good ol' cycle of once-decent products ruined by management and market forces demanding software updates.

No, but do you have anything to combat induced nausea? I'm working on a video that shows how field lines move through a remarkably small nozzle-like region, where plasma and magnetic flux are allowed to pass between two topologically-distinct magnetic domains. It's like where you'd glue a paper Mobius strip together. Simple-ish. But the surfaces of the magnetic field separatrices, which extend away from there, are very 3D, with a pretty complicated geometry. Some may puke. One sympathizes.
Sorry, we've gotten wayyyyyy off topic, but I just don't know what else there is to do, quarantined here in these threads like this. This post, this is our home now. Yes, yes, we need to also simulate a quarantine on Hubski to... um, to equalize the karmic balance between the reals and the cybers in our minds.
