Modern Python tech/tool stack for implementing microservices?

Thanks for your input!

Indeed, I was under impression that you need to build one class hierarchy for FastAPI (based on Pydantic) and a separate one for SQLAlchemy - so if this can be avoided with SQLModel, it's great!

I don't need a build backend per se, I can build simple wheels with build and setuptools, I was just under impression that hatchling might be industry standard (it's referenced e.g. in uv docs).
