Observations on using the Apple Studio Display with Zoom.
The camera needs more light during daylight hours, currently supplied by the ring-light part of the old webcam. It has three touch selectable levels of illumination. It has an array of three microphones, together they don't sound as good as the Audio-Technica USB condenser mic I used to use so that's my go-to audio input device. The speakers are excellent, totally replacing a 2008 Logitech 15W USB subwoofer 2.1 stereo speaker setup. Now I have to find a use for that speaker setup, it's still very effective. The webcam in Centre Stage mode is inadequate; I prefer it in "normal" mode. If necessary I can use the iPhone's rear camera as a webcam via Continuity Camera. In Zoom, once you get more that about 5 participants, their effective webcam resolution drops to around 720p levels anyway.
It integrates so well with my other Apple gear, I can accept the high price because it has the promise of working fine for a decade or more as well as replacing other stand-alone peripherals.
