Do you have any resources for this? especially for the adhd kind - I end up going down rabbit holes in the planning part. How do you deal with information overload and overwhelm OR the exploration exploitation dilemma?

There are 2 bad habits in programming: people that start writing code the 1st second, and people that keep thinking and investigating for months without writing any code. My solution to that: just force to do the opposite. In your case: start writing code immediately. Ni matter how bad or good. Look the youtube channel “tsoding daily” he just goes ahead. The code is not always the best, but he gets things done. He does research offline (you can tell) but if you find yourself doing just research, reading and thinking, force yourself to actually start writing code.

Or his Twitch videos. That he starts writing immediately and that we're able to watch the process is great. Moreover the tone is friendly and funny.

I wonder if good REPL habits could help the ADHD brain?

It still feels like you are coding so your brain is attached, but with rapid prototyping you are also designing, moving parts around to see where they would fit best.
