There's a Zoom setting to Mute Attendees Upon Entry. I make that my default for every meeting. Some people complain, but I've had way too many people join and not realize their mic is live, so the meeting is interrupted by random dude shouting at his children to stop making noise, etc. Or even better, when the meeting tool has a "Call me at this number" tool, but does not require validation before bridging the audio. So instead the CEO's All-Hands PowerPoint presentation is interrupted by that one guy who tried to have Zoom/WebEx/GoToMeeting call his cellphone, but the call goes to his voicemail instead and the voicemail audio plays over the (recorded) conference. Fun times. I've seen it happen multiple times.
