So I recently started working on adding the features of a local high school into a relations group, but after looking at the docs, I’m not sure I’ve properly understood when or how relations should be used. Could somebody help clarify this?

For a school thats on a single site, the usual practice would be to add the buildings (building=school), playing fields, carparks, driveways and footpaths, then draw a single area around the whole site. That site area would have the name of the school, and all the other school-wide items (address, website url, etc).
You might need to use a multipolygon relation if there are two sites associated with the same school. Perhaps the same school has a main site and a set of playing fields nearby. Or maybe a multipolygon relation for one if the buildings, if it has an enclosed courtyard.
But in general, there’s no need for a relation. Even if there are multiple schools operated by the same organisation.
Normal School (no relations) : osm.org/way/454984390
Multi-site school (a relation) : osm.org/relation/10999945
School building mapped as a relation because it has an enclosed courtyard. But the surrounding school amenity is not a relation: osm.org/relation/6542927
