I would suggest going with a dynamic USB mic, something like this. There are higher end options to like the Rode Procaster or SURE SM7B. But that Audio-Technica would do the trick.

You'll want to stay away from condenser mics if you're not in a full recording studio setting as they capture a lot more noise (from feet tapping to things moving to outside noise or loud fans/AC, etc.).

And, if it's just you, a Ring Light like this could be helpful.

I'm not as well versed in video, but you could capture a second angle with a phone camera (if your phone has a good camera).
