I think the MCU is just in a really weird space.
It took 11 years to get from Iron Man to Endgame but those films really feel like they built up to it, especially from Civil War onwards. The Guardians entering the Avengers storyline made perfect sense in Infinity War. We have like, a new version of the Avengers and I don't know how they will merge with the Eternals? Plus stories like Guardians, Thor, AntMan are still ongoing.
There's a lot of promise as to how these stories will intertwine - the Shang Chi end credits for example. There are also exciting new characters like Eros and Clea. It's just not easy to envision how the likes of Yelena, Kate Bishop, America, etc. will all continue beyond this point. We have a general idea of the films coming too, and it doesn't seem like this will happen in the next 5 years.
I became an MCU fan quite late, 2017, when it already felt like this was leading to something. I just think without a clear leader like Iron Man or Cap, half the stories taking place on (mid) TV series, it's not as straightforward as the Infinity saga.
Maybe it makes sense if you love the comics. I know fans talk about Secret Wars. I just hope we get a big team-up event sooner rather than later, and some of these new characters we've started to love pop up more.
