I think the OP meant options that are as "easy" as click on a link and join a meeting. I use BBB and Mumble but there are others I know who would never know how to set up their own instance or even what github is.
jitsi is exactly that, been using it for the whole pandemic for meetings for my team of 10 ppl, never had an issue.
Jitsi won't consistently work at scale and is (like most webrtc only applications) a terror to debug. You can basically forget about using it with someone that has issues.
This is why multiple companies exist to sell you one-click hosted instances of these without lock-in.
