If your experience is limited to academic projects, grinding leetcode, even competitive programming, you've done things where first one is nearly always optimal.
Once you are on a team optimizing for continued feature delivery over time, the cognitive load of picking up and understanding old code full of raw maps and strings starts to justify the overhead of a bit more semantic scaffolding in places.
IMO the necessary judgment has to be learned even by smart, academically talented people.
I'm also finding myself more allergic to unnecessary code complexity / non-standard designs, because they impede my ability to work with the code base.
It's still a little painful to no longer be the smartest person in the room, but I think it makes me a better champion for regular programmers who will need to touch the code.
I may not be the "smartest" in the room in terms of raw compute power of my brain, but as a result I'll write better code (more maintainable, easier for the next dev to understand). I want my code to be easy to follow. One of my personal rules I have through experience, is if I revisit a bit of code that I wrote a while ago, and I can't understand it easily, it's probably time to refactor it.
I've rarely worked in a team where the extra scaffolding was ever worth it. In fact chasing the scaffolding scattered through varied files through the filesystem was a lot trickier usually than fixing the actual bug I was trying to fix.
I feel like self-contained, self-describing, potentially self-validating data types like in the parent comment would tend to be complexity-reducing as long as they don't mix in control flow or deep deep inheritance hierarchies, though.
