For my private setup I use my Truthear Zeros with a Samson Q2U microphone (USB). The Zeros doesn't suffer from any sound leakage and the Q2U doesn't pick up much background clatter, which is good because I mostly use that for gaming where you'll hammer the keyboard a lot whilst communicating. Gaming apps (Mumble and Discord) are pretty good at removing the little background noise that does come through.
For work I use a Mac, so I use the old 3.5mm headset from Apple together with the built in voice isolation feature of MacOS. I find that Voice Isolation does a good job at removing unwanted background noise, especially compared to the typical corpo meeting apps built in features (really, it boggles the mind how far behind corpo apps are in this regard), but perhaps not as well as RNNoise or Krisp. For video, I use a Raspberry Zero with the Raspberry HQ camera as my webcam. Been wanting to try the continuity camera thing Apple released recently but I don't have a new enough spare device for that.
Hardly any fancy hardware in either setup, but it sure sounds and looks better than just about everyone elses setup that I suffer every day. Figure that the voice quality mostly boils down to using effective noise removal on your mic input. On that note, I recently tried AMDs noise removal that they introduced with their 6000 series of GPUs, and it is truly useless.
Edit:
@m_g_s_g Haha, what are the odds - same mic and headphones.
