To me, the most important point of your post is
And, finally, I am in the process of comparing my results and code with File::Find. I certainly appreciate File::Find more than I did two weeks ago.
Reinventing the wheel by going in a random direction can cause extremely bad habits. Taking your version and comparing it with a working version helps to moderate that effect.
Unlike some of the advice here, I think this is a valid and very effective approach to learning, as long as you don't forget the production wheels that you can learn from. You also have the opportunity to rewrite your code after the comparison to see if you really learned what you believe you learned from File::Find.
As professional programmers, it's easy to lose track of the need to practice. Rewriting code that is not needed for production can help you learn and help keep your basic coding skills from getting rusty.
It also helps to remind us of the sense of accomplishment that we used to get from making something small with our own two hands. When working on big production systems with multiple programmers and man-decades of work, it's hard to remember the simple pleasure of making the computer do something for me, as opposed to keeping the system up and functional.
Good luck in your explorations and don't forget to share your experiences with your fellow monks.
