It depends, so I'm asking you some questions to give you ideas.

How much of this code is going to be read, reused, modified, studied by you or other people?

Is it opensource or foundational?

Is it of any interest for the general public?

Could you actually spend more time in doing something else which is more productive?

Is this refactor make you learn a new tecnique?

Can you find or develop an auto-formatter that makes messy code just neat and clean?

If you are building models for a process or phenomenon, can the results be the subject of an article, maybe in the future, to show your tecniques and ask for feedback? Notebooks are just great for that.
