It sounds like what you might be after is some content on crackmes/specific RE challenges. I'm not involved in that space, so someone else probably would have better links, but one challenge that was my start in RE was the Synacor Challenge: https://challenge.synacor.com/
It starts off just as a programming challenge, no real RE knowledge required, but if you see it through to the end you'll definitely wind up with a bunch of foundational RE skills. And there are a whole bunch of public writeups online if you want to follow along with someone else's approach.
(Just to note, though, that it's based on a custom CPU architecture – implementing that is the programming part of the challenge – so very much from the ‘learn it the hard way so when you do regular stuff it feels easy’ school of thought.)
The Youtube channel LiveOverflow also has some videos going step-by-step through some RE puzzles, and his content is very digestible.
