Idk, the other TES games have all the archetypes you listed, while Morrowind's topography was immersion-shatteringly simple and fake. With the exception of Red Mountain, the world was unrealistically flat, and Bethesda put arbitrary fog in the game to hide just how small it really was. One of the last things you do when modding the game is increase the view distance, but it's a double edged sword in that seeing how close the major landmarks really are makes you feel like you're in an amusement park rather than an open world. It killed the wonder and curiosity of exploration for me, while Oblivion and Skyrim didn't need smoke and mirrors to assure you that you're in a fantasy world brought to life.
Of course the silt striders, the telvanni strongholds, the canals of vivec take care of that well enough on their own, perhaps to a stronger extreme than Skyrim's graphics can. Unfortunately, Morrowind suffers from the burden of being a video game, and it just doesn't have the gameplay to back it up. Even the simple act of moving is a painful experience, a problem modders have tried to solve since the games release over a decade ago and haven't quite figured out.
I beat Morrowind and Tribunal, so obviously that says something about just how strong the story and aesthetics are if I spent that much time with the game. But there are games that have everything Morrowind did along with fun gameplay to boot, some of which are lower ranked on your list.
