For Oxyde specifically, it's still a young project, so the best public examples I have are the FastAPI tutorial (https://github.com/mr-fatalyst/fastapi-oxyde-example) and the admin panel examples (https://github.com/mr-fatalyst/oxyde-admin). Bigger real-world showcases will come with time. But in general, ORMs pay for themselves when you have lots of models, relations, and standard CRUD with validation. The moment you hand-write the same INSERT/UPDATE/SELECT with joins for every endpoint, it adds up fast.
