Publii is more a blog-oriented static CMS, but this does not mean that it only supports blog sites, you can create other, still simple but a different than a blog:
It has no concept of pages
Publii has built-in support for pages called Hidden post – it creates a “static page” that is excluded from any post listings, it also supports custom templates, so you can define your own HTML structure.
@maa If you need a more comprehensive solution for your needs, I agree with @jakobpersson you should use a different static generator.
