A free, libre, opensource, and privacy focused alternative to Zoom is Jitsi, which can be used without an account.

How many of those support captions?
I’m not sure which use case you’re referring to specifically, but I have not used any caption functionality in any of the services listed. However, I was able to find the below documentation. At a quick glance, it looks like Jitsi and BigBlueButton support captions better than Jami does.
Ah, good to know! I don’t use meeting platforms that aren’t accessible by default for everyone. Looks like the problem, at least in Jitsi, is that enable captions defaults to off. It would need to default to on before I could use it.
What do you mean by “defaults to off”? The links for Jitsi were just to how it’s set for recording. However, closed captions seem to be turned on by default already. I think that may be more what you are looking for?
Based on the links you gave, it seems that captions default to off when new servers are created.
