The downside of the mixed approach is, as an earlier commenter said, that you can end up with an "us vs them" mentality, where the people who see each other every day and get to have small-talk and get to know each other grow closer and then the people who work from home are somewhat on the periphery. I've seen this before, I've been working remotely for a lot of the last 7 years and there's a distinct difference in social dynamics. Even if the people in the office need to use Slack or whatever for communicating, they have their in jokes that they sprinkle in and you can feel a bit alienated or ostracised if you're in a minority of work-from-home employees. Equally, if some people are not able to work from home, that can build resentment or envy. So the company culture can be affected by different amounts of in-office vs home-office, every company will have their own sweet spot, but I agree with you, there is no simple one size fits all solution.
