I mean, isn't that what this is? Components for layout?
Personally I prefer MUI over Tailwind (there is layout overlap there, but MUI is much more than layout). But either one is much nicer to use than raw CSS when you are composing complex pages and dashboards. It's like you said, working with higher level components, just with layout also mostly finished out (but both frameworks let you adjust things in-situ like padding, margins, font sizes, colors and such in a clean and maintainable way)
