Is it primarily useful just for data visualization? Would there be an potential performance benefits for something like searching a database for nearby data?

Yes, such indices (S2 & H3) are widely used for providing a index in databases, so geospatial features that are close by in the world and stored in nearby databases rows. https://cloud.google.com/bigquery/docs/grid-systems-spatial-...
