One big category that's missing is the quick, informal after meeting sync. When we were in the office, after big meetings, I would usually chat with my juniors about what happened. What went well and what went poorly, the general theory of how those kinds of meetings work, that kind of thing. That's much harder to do now, so I mostly don't, and as a result our post-Covid newbies are generally worse at running meetings.
