I think we all want 3 things -

1, back-end services with clear boundary, that decouple concerns based on dev teams' domain responsibilities, with less dependency among each other,and respected source of record. This is very much the "micro-service" is for.

2, middle tier services to consolidate or aggregate back-end APIs to serve the front-ends (especially the mobile apps) and take care of the business logic. Back-end guys all love micro-services, but someone must put them all together....GraphQL so far seems to fit this bill

3, Analytics and reporting, this is a totally different animal from the product development, and have almost opposite requirements. This is where whatever your ETL or Data Lake or Data Pipeline is used, along with your preferred BI or analytics tooling.
