So far, after some days of testing, the only solutions I found are:
- Using a continuous voice typing keyboard app on my Android to transcribe into a Etherpad document, and sharing that.
- Livestreaming the Jitsi meeting to YouTube (auto-captions require 1k subscribers, though)
- Giving up on Jitsi, and just using Zoom / Google Meet / whatever else that has this out of the box
Also, if anyone was using Jitsi and moved to something else entirely, I'd love to hear about those experiences.
