If a single game were to try and implement all of what you said, you'd find that it would no longer be conducive to being an MMO and barely even an RPG.
What it sounds to me like you want is something more like Dungeons and Dragons but in game form. Such games do exist, though they are mostly on the older side of things now since that gameplay style has gone out of favor due to how quickly it becomes boring to some people. The next closest thing I can think of are survival games like have become increasingly popular lately, but they tend to be more focused on creating your own world within a world instead of surviving in an already existing world. If you've not played it, I recommend the game Kingdom Come: Deliverance as it includes some of the things you mentioned.
Lastly, on the topic of features such as dynamically spawning NPCs and interspecies relations and stuff, at some point you have to consider the very real fact that most players would not even notice such features, let alone be directly impacted by them. Sure it sounds great and realistic on paper, but just like, say, Geralt's hair dynamically growing in the Witcher 3, does it really matter beyond saying, "Oh hey, his hair is growing, that's cool," once or twice?
