There is an industry that packages high quality Sony image sensors in packages with C or Cs mount lense compatibility and native UVC support on Linux/MacOS/Windows. Primary uses seem to be industrial cameras for manufacturing quality inspections, circuit magnification for repairs, installation onto telescopes, etc.

Prices range from $40 to multiple hundreds for extremely high quality sensors.

This sketchy site has comparisons of the sensors by area and signal to noise ratio.

I bought a 1080P one with very high SNR and 2-14mm lens using the Sony IMX291 sensor for $79.

For audio, I bought a Samson Q2U USB/XLR mic for $60. USB has been perfect, and the included stand works fine to the side of my keyboard.

Altogether, this is a cost effective way to increase audio and video quality for meetings / streaming.
