One issue you did not address in your otherwise solid article is the issue of audio sync latency IF you don't pass your audio via the camera's HDMI. This becomes an issue when you decide to use a nice mic/audio interface for higher quality audio but then you can have sync issues with the video. To mitigate audio sync issues, it's best to have the audio going into the camera's input. You can pass audio from a nice mic/preamp into the camera but it's less ideal than going into the computer via a decent audio interface. Afaik, OBS can fix those sync issues but it's quite a lot of effort to do all of this properly vs. buying a better webcam.
