I'm in a situation right now where my office is near by and open, but attendance is mostly optional and ad hoc. I find that days when I have lots of meetings are the best days to WFH because it's so much easier to talk over Zoom and not have to rush back and forth to meeting rooms. Having a chat window secondary to the out loud talking is also invaluable. The in-person situation is most valuable when I'm working on some tactical problem (ie coding) and want a second set of eyes or just to complain for a minute. It can be done over Slack, but it's less natural.
