For video, choose cameras with multiple codecs, like H.264 and H.265, that transmit your video smoothly (not choppy) so other attendees see you clearly. Look for advanced features in focus and color rendering plus quality components like a glass lens. Lastly, consider the size of the meetings space and look at the field of view (fov), PTZ, and auto-framing features. In a work from home environment you may need a professional webcam but for a hybrid office a huddle room camera would likely be a better fit.
In audio endpoints you'll want to focus on both microphone range and speaker volume depending on the size of the room. Look for full duplex which will allow you to speak more naturally and be heard even if others are talking.
A final point to consider is connectivity. Look for USB driven devices that are plug and play and can easily transition from meeting to meeting depending on your organization's needs.
