Export to HTML is usually a decent report. If you want to refine it a bit, you can export and show only outputs, or (with some code) only certain tagged outputs.

To plug in new data, I experiment with papermill.

There are solutions that can put jupyter and the kernel in different environments. It's even not too hard to setup, but it astounds me it's not a common way to set it up. It's natural to have kernel + the analysis's deps in its own environment.
