As someone who uses Astro a lot for (mostly) static pages, the two standout features of this approach that come to my mind are code sharing and the ease of integrating SSR/CSR where needed. Components (be it Astro, Svelte, React, etc.) have a lovely API for sharing code across web pages. I used Hugo before and hit the limits of shortcodes pretty quickly. I can't comment on Jekyll though. Furthermore, if the need for some dynamically rendered pages or client-side interactivity comes up, it is very easy to integrate this later on. I can build static, server-rendered and client-rendered pages (and everything in between) with the same set of tools, which means less mental load when I develop.
