For content, I would recommend not a webcam. But if budget doesn’t allow something better, I’ve had pretty decent success with Logitech webcams for simple meetings (which we record) that have pretty nice picture.

4K resolution doesn’t mean much with webcams. I’d look for clarity and color reviews as the quality of the sensor matters much more than the resolution above 1080p.

I’m sorry for not having insight into the exact models. If you have budget for a real camera at any point, I can be much more specific.
