I think the sweet spot is, let teams decide how often to meet if you're going that route. For example, last place I worked at we were mostly from various parts of the states, so we were considered remote, whilst others lived nearby and had to commute. I think managers should decide wholly how their teams work. If managers need to be onsite, that's reasonable too, though I would assume not always especially if their teams are remote.

I feel like the less technical teams might benefit more from face to face, but developers, a lot of us do our coding at home before our careers even start. It is a hacker's career path.
