I’ve never seen any reliable service built on a NoSQL store as a primary data store. If data consistency and not losing customer data important for you, RDBMS are just fine.
Data consistency was solved in Mongo and DynamoDB years ago. CQRS is a better pattern. Read Models out of analytics (relational) data stores are better for dashboards. I stopped being "SQL First" ten years ago and never looked back. Saved clients time, money, and improved maintenance and eased feature additions.
