I retired right before COVID hit and I'm sure I would've hated working from home in my old job as director of process development with groups of 20-30, typically. In that job, I used to walk around the floor where all my folks were a few times a day, checking in on things in the lab or pilot plant or just on any key issues and those conversations would often lead to impromptu hallway "meetings" on these key issues, often resulting in brainstorming that led to important ideas and solutions - and some of those discussions were much richer when they took place "on the floor" (gemba) where the work was being done and actually seeing how some reaction or process (or troubleshooting problem) looked in the lab or pilot plant.
Or sometimes emails led to a walk down the hall to further discuss some breaking issue or problem. And occasionally, these one-on-one or small group discussions occurred in "reverse" when people would stop by my office. I can't imagine being able to do this kind of informal brainstorming and problem-solving nearly as well remotely, as I got to see how inefficient that was when working with our remote contract labs or manufacturers abroad, where video/teleconferences were the only realistic way to get things done. The other benefit of in-person conversations and meetings is simply better relationship building. Most of the people I know in my old area like the flexibility of WFH, but are glad that most folks are back on site with regard to getting things done.
