Yeah - I agree with both of you. First start with the boilerplate approach, and once there is boilerplate in place for a low number of entity types, say, 2<n<10

Yeah - I agree with both of you. First start with the boilerplate approach, and once there is boilerplate in place for a low number of entity types, say, 2<n<10, figure out if that can be refactored into something less boilerplatey. But yeah, very seldom starting with a complex abstraction for a code you've never written before is a good idea.
