All the things you listed were already done over email, slack, etc. even before the pandemic. The moment I have to involve a second team, I have to do it over email, doing it in person is too disruptive to work.
Don’t you find though that people will eventually bring emotion / drama to a discussion on email, which immediately gets blown out of all proportion because email?
Those kinds of situations are much easier to keep on track in a call / video conference, and easiest in person, when you can have ad hoc conversations after the meeting has ended. (Video conference products I have used — all the standard ones — don’t really have a way of ending a meeting other than hard-stop-return-to-isolation for all participants, whereas in real life it’s much smoother and more continuous than that.)
