I have one browser that I use for work email and video conference, where system grants access to camera/microphone to the browser and browser allows Google Meet to access camera.
I have another browser where system does not grant access to any of the devices - camera, microphone, USB etc - and I use that for web surfing.
And I strictly don't install any plugins for video calls. I have refused to join meetings where people try to make me install random binary software on my machine. There's always phone call for such situations.
I feel better about dedicated apps on iPhone where again I can install and grant permissions before the call and then uninstall the app completely. On iPhone I don't do any web surfing. I have Firefox Focus for occasional emergencies to open the unknown web.
