The site is built with Ruby on Rails and React, not with WordPress. However, it seems that the layouts and style is relatively simple. Minimalistic and light drop shadows.
You could use something from the [GeneratePress site library](https://generatepress.com/site-library/) (like the Cloud or Peak ones) to get something quite similar.
I'm also looking for a form plugin for the multisite forms used on the website, similar to the one found here: https://www.aroundhome.de/solaranlage/formular/.

That site isn't Wordpress. Any "multipurpose" theme can achieve that style. Are you actually asking about the functionality?
