Great stuff!

We moved to microservices, despite my love for a monolith with libraries: - to enable different teams to deploy their smaller microservice more easily (without QA, database migrations etc affecting the whole app); - to solve the human temptation of crossing abstraction boundaries.

Not black and white, and both approaches can solve these problems. Open to any feedback!

Yeah I moved to microservices for the exact same reasons. People are undisciplined, and making it harder (and much more obvious) for them to do the wrong thing is more important than having all your code in one place. Plus, if you need to upgrade some dependency or if you want to try a new language or library or idiom, you can do so without the risk, effort and sunk cost of upgrading the entire application.
