It never ceases to amaze me how companies choose the worst software!

IANAL, but it seems like that would include training on your data as long as the model was used as part of their service.
Everyone who operates a video conferencing service will have some sort of clause like this in their ToS. Zoom is being more explicit, which is generally a good thing. If Jitsi wanted to be equally explicit, they could add something clarifying that this does not include training AI models.
You would be well advised to use services where the traffic travels through https on port 443 on the server (because it's been my experience that it tends to get pretty good QOS favorability). My own little rule of thumb: "you can connect to any port you want, so long as it's port 443 https." ;)
Though tls/443 is usually still supported because it's most often allowed by even restrictive firewalls and networks
