At one of my previous jobs, they had a "BOM" that each service inherited from. This contained most of the core dependencies (Spring, database drivers, logging, monitoring, auth, service discovery etc.) with a default configuration that worked in all environments. This was built on top of Spring Boot, so if you needed to use Postgresql, you just added the basic database configuration to your property file and the BOM would make sure that the necessary beans and service discovery was loaded.

This meant upgrades were usually as simple as increasing the version, as the infrastructure team had already made sure that the other dependencies had been tested. Each team were free to ignore this and do whatever they wanted, but the benefits were too great to ignore for most teams.

At my current job we don't have this type of shared configuration, which makes micro services much harder to maintain.
