We found our sweet spot in terms of enabling the flexibility of front-end devs experimenting and defining their own queries while maintaining cacheability. During development, front-end devs use the Graphiql endpoint to play around with the data and figure out exactly what they want. Once that's settled, we turn it into a persisted query that is stored on the server and keyed by a unique ID that the client apps use in production instead of the raw GraphQL payload. You add a small amount of overhead for the coordination to create the persisted queries, but we're considering even building a self service process in the future.
