What is the most fair way to meet in the middle?

For two people, the midpoint is straightforward. For groups of 3+, use the centroid — the average of all coordinates. MidMeetup does this automatically and then ranks venues by combined travel time, not just distance.

Fairness also means: nobody walks into a venue that's closed, fully booked, or in a parking dead zone. A good midpoint tool checks for that too.
