I am using Hikvision DS-U02 3.6mm Optical 2MP 1080P HD it's very good webcam for Zoom & Teams Meetings. No issues so far, the only thing I have noticed is that sometimes I have to unplug and replug it once in 3-4 months
No, unfortunately this monitor doesn't have the height adjustment but you can tilt the monitor front and back and also there is no 90 degree turn Option
