The advantage Marvel has that a lot of people don't realize is that Marvel's IP is not one thing. Yes, it exists in a shared universe, but it's a universe that grew out of a comics publisher that was doing crime, mystery, Western, romance, sci-fi, fantasy, horror, comedy, etc. before it started building the Marvel Universe proper in the '60s, and ended up folding all those different genres into its nominally superhero-driven universe. So Marvel Studios has a very wide, eclectic base of material to draw on, spread across numerous different genres and appealing to numerous different audiences. It can still do works that completely stand alone as their own independent things, like Moon Knight, or Eternals to an extent. Yet at the same time, it's built up this incredibly rich ongoing continuity and history that any of its new projects can draw upon as needed, something essentially unprecedented in film history, or at least never done to this degree, encompassing so many works with such consistent continuity.
So MS has just about as wide a potential range of subjects and genres to draw on as any other film studio, but with the ability to use them to reinforce and support each other. I see no reason to imagine that ever has to stop.
