Ask HN: Monorepos for Data Engineers?

Hey folks, I'm working with a data engineering team trying to consolidate all their misc projects into a single monorepo. I'm used to working on monorepos in the context of regular software engineering (e.g. at my company, our monorepo is Golang, Rust, and Next.js and we use moonrepo to manage everything); however, not so much in the context of data engineering. It doesn't help that I'm not as Pythonic as I should be :). Wondering if there are known best practices I should be aware of for managing Python monorepos in the context of data engineering?
