shameless plug, but at my place of work we recently relaunched out web meetings software. One of the design goals is that Meet (which is the name of this new piece of software) will eventually work without the need to use the rest of our stack.
Architecture wise it only depends on openid connect for authentication (we provide Konnect for this which can also be configured to get its users from LDAP) and our rest api to get contacts from your company. (and then naturally you also want a turn server from cross network calling).
Compared to Jitsi we are still missing some features, like guest users and screenshot are still in development. On the long run we also want to add a feature similar to the "videobridge" that Jitsi is offering. But looking at the linked docker-compose Meet seems easier to deploy.
