More seriously, it depends on what exact part you want. Matrix + Jitsi work for chats and calls, though they are a little shaky (but so is Teams sometimes, I don’t much see the downsides). Calendar apps are a dime free a dozen.
What other tools often lack is the direct between multiple services. You’d have to manually link a NextCloud directory in the Matrix chat, bevause it doesn’t have a near seamless sharepoint integration.
The upside is independence: You can migrate between hosts, or host your own instances of NextCloud and Matrix, entirely within your (virtual) private network. And those are just services I can name off the top of my head, odds are there are plenty of other good solutions.
