Does Zoom support 4K webcams?

Zoom transmits at up to 1080p on paid plans and 720p on free plans. A 4K webcam still looks better on Zoom because the downscaled image is sharper and cleaner.

Do I need a separate microphone with a 4K webcam?

For casual video calls, built-in webcam mics are adequate. For streaming, podcasting, or professional calls, a dedicated USB microphone is a significant upgrade.
