I'm pretty interested in this: https://opalcamera.com/

There's been a vacuum in high quality web cameras for a while, most of the market has just been junk.

A good microphone is totally worth it too. I'm not sure why after over a year of pandemic and remote work many are still using their 720p webcam in a dark (sometimes backlit) room with the crappy built-in mic. If you're making good money invest in a decent set up - with mostly remote comms, it matters more than you think.
