Fair enough. I'm highly biased and my recent book is the most popular Pandas book currently, so it is evidence that folks prefer opinionated documentation.
However, I always though the 10 minutes to Pandas page was decent for getting started. I picked up Polars recently and thought it was more difficult than Pandas because there wasn't any quick intro docs. What projects have great introductory docs for you?
Also, I am curious to learn more about the specifics of interop libraries you are referring to.
Learning a new tool is generally a challenge. I think another challenge with a lot of data tools is that non-programmers tend to be the major audience. I make my living teaching "non-programmers" how to use these tools.
That said, I always teach "go to the docstrings and stay in your environment (to not break flow) if you can." The pydata docstrings are better than most, including Python (the language).
