If you already know and you're familiar with Vue, why don't you use Nuxt.js? You can generate a SPA or a PWA if you don't want to have the SSR version.
Yeah good question, maybe it feels overkill. I also found Gridsome which also looks very interesting
I’ve found for small sites, building a vue SPA and using react-snap to generate the pre-rendered static pages works great, and cut out a lot of the overhead I felt with gridsome.
