Hi, My own view of the building tag is that it notes what the building looks like to someone on the ground. If it's a fairly generic building then obviously the current use is a fairly good indicator. Something like a church or pub though often still retains the characteristics of that type of building even when internally converted. As long as it still externally looks like a church or pub that is what I tag the building as.
