I keep mixing up the options, but I think multi-region support is important for global applications, which makes me lean towards Cloud SQL or Spanner.

I'm not entirely sure, but I feel like Cloud Spanner might be overkill for a read-only application.

I remember we discussed SQL-compliant databases in class, and I think PostgreSQL is a solid choice for this scenario.
