It's the "USB audio interface" part of my list. Take multiple inputs, do some processing onboard, send it down a single USB cable to the computer. It will take anywhere from 1 to 4/8/16 XLR/line/instrument inputs, with headphone out and monitoring of inputs. Here's what I use:
It's overkill for online meetings, in that many of its features will go unused. It's a well-built box, though, with better build quality than the (cheaper) Presonus it replaced. If there's just one mic or input, and some headphone output, then something like this would be less expensive (and less to fiddle with):
Now, for under $100 (surely you have some wired headphone lying around) you'll sound better than 95% of everyone else in online meetings. That's why I have no recommendation or ones to avoid, because for online meetings all it has to do is what it says on the tin to be better than what you've got now, and "good enough" for online meetings. If you're into music, then we can talk about which one is better over another (and frankly, I'm not the one to ask).

That's the first single input, inexpensive audio interface I found on Sweetwater; just an example, not a recommendation.
Add to that a cheeeeaaap dynamic mic:
