We used to have people in the office in a meeting room, and remote online, but this has changed in our case at www.comeet.me. Now, everyone goes online, as the experience is better and more respectful with everyone!
I have been a remote engineer for 10+ years but honestly getting a shared office with a meeting room these days is so easy that I almost always select that for important meetings. Meeting in person is such a great thing once you have worked remote your entire adult life. The balance is key.
If the meetings are daily or weekly rituals then I think online or a mix is fine.
