I haven't used Teams, but I regularly use WebEx, Zoom and Skype (though not Skype for Business) and I hear around the workplace we're likely to have the option Bluejeans soon.
For me, good video conferencing software has the option of showing the full participant list without needing to scroll through photos. It will have the option of focussing on the speaker or a grid view. It will have the option of pinning some speakers (I think there's usually a maximum of 4.) It will have the option of the host being able to mute all. And it will allow only competent uses to share slides/screens. (Some of that is a host/user issue more than the tech.)
I would not allow anyone to use their camera if they don't look at their own image to ensure they aren't looking up their nostrils. I have also seen about a million ceilings in the last couple of months. You can check your image, and you can put your laptop up on books if that helps the angle, and usually you can move your camera angle (which is usually somewhere around the screen these days, so move the screen) so that it's looking at you straight on. Actually, in most meetings, I don't turn my camera on - there are certain ones I do, but it's an active choice, not default. I also prefer people to mute unless they're speaking, because keyboard sounds are annoying, and because if they're on speaker rather than headset, there's usually some feedback as it picks up the audio again, and because too many people have been caught out saying ... untactful things when they weren't on mute, but weren't the focus of the meeting, and people clearly need to think more actively about it.
Meetings, in whichever format they take, be it physical, video, or only audio, need a good chair, and there are not enough of those in business. A good chair will make sure everyone gets the opportunity to speak. If you're a woman in STEM, you do need to learn to be assertive and thick-skinned, but it can be difficult, especially on virtual meetings.
My employer has been good at ensuring all the managers have training around unconscious bias - IMO, they need to ensure everyone else gets it, too. Culture may be set from the top, but the bulk of people (and thus those who really affect it) are not at the top, so they need awareness of it, too. Although in my 20 years as a techy, I've seen plenty of conscious bias as well as the unconscious type.
Here's one example of sexist AI - and that's from Amazon, who must be one of the major users and coders of AI that currently exists. There are plenty of other examples if you google.
