Google Meet, which is available to all users of Google Workspace and consumer Gmail users, is an easy to use online meeting application. As do all meeting apps, Meet supports camera, audio and screen sharing.
As far as audio hardware goes, there are a number of options. Some work better than others, depending on the environment the meeting host or attendee is in.
Keep in mind that just one attendee who introduces too much ambient noise can degrade the meeting experience for all attendees.
