For a MVP, it's hard to beat Phoenix Framework channels and Liveview, and if you want to completely decouple the UI from the backend with something like a native app, or separate webapp, it's absurdly easy to just add the resources to a route that goes through the :api pipeline instead of the :browser.
Once you are ready to outgrow a single machine deployment, the BEAM clusters so well in a way that works the same on your dev machine. Also if you want to get really complicated multi-service design, Umbrella apps are leagues better than docker-compose setups that I have had on dev machines that make a 16G Macbook pro instantly put everything into swap.
Half of the reason that I enjoy using GNOME, KDE, and other distros is that I can theme the entire system for a relatively consistent experience. I enjoy having system apps all be the same configurable color theme and even design language with flat themes and material themes becoming popular.
Layouts might be a bit much, but themes are a key part of the user experience.
