What, in your opinion, would really make exploration shine?
(apologies if I missed your specific ideas somewhere in the 36 pages here)
Honestly? I don't know. With the way the game is written and the "expected challenges" of traps I can't really think of any way to do it without completely rewriting the game.
The best version of traps I have found is the "click" method, I think from Dungeon Dudes, which basically allows the players to react to a trap being triggered to try and avoid it by declaring an action. It still doesn't really solve a lot of the bigger problems with traps.
Puzzles and Riddles are a constant headache, and I've tried to figure out a way to utilize them that isn't just challenging the players while they take a break from DnD.
Resource management is fairly boring, but mostly it is a solved problem. Barring needing a wagon to carry water (and then hiring a small army to care for the wagon and the mules) it isn't something that is a challenge I've found.
But, perhaps the biggest, the game just doesn't make the world fantastical enough. Most exploration problems are things handled the same way at level 2 as they are at level 5 as they are at level 17. The numbers get bigger, but the actual mechanisms rarely change. And there is no "dangerous wilderness" past around level 5, it simply doesn't exist.
The closest to something really good I've found in 5e so far is the Tasha's environments, those are a really cool idea, but a lot of it is still wandering monsters to fight and traps that hit your hp. It doesn't offer a lot of options, not in the way I was hoping.
As was said, the best parts of exploration are when you are discovering the context of the adventure, finding the clues, but you can't make mechanics for that. You can't make mechanics for descriptions.
so, I'm really not sure. There are a lot of different problems, and I'm not sure there is one solution.
