I am trying to combine the audio from my microphone (either built in

I don't know much about Linux audio internals and wasn't sure how to
do this. Can I do this completely via the operating system using
Pulse Audio? Do I need to do something with Jack? Or do I need
specialized software such as OBS, Ardour or Reaper?
OBS is probably the easiest way. You can add your local video if
needed as well. OBS will work fine with just pulse or jack. I don't
know much about jitsi it self but if it uses pulse as the default
device there should be no problem.
I just checked the Jitsi Meet using Chromium (they recommend
Chrome/Chromium, apparently Jitsi uses some newer streaming standards
that Firefox either doesn't fully support or is just simply too slow).
For microphone, it offers my USB headset, USB audio, Builtin and
Pulseaudo JACK source. Which I remember I do have Pulseaudio set up here
feeding to JACK sink. Output include the preceding plus PA Jack sink.
You are probably using the module-jackdbus-detect in pulse. that by loads
the two modules jack source and jack sink. However you can add as many of
those as you want. Also, it seems pulse can see other devices but using
zita-ajbridge they can become jack devices and mixed there. Then all
become part of jack source.
