Our website is a large global webshop and uses SAP Hybris as a CMS; however, we're now developing a significant content arm and want to also have a landing page/content hub for daily articles, videos and updates, a bit like a news site.

For this it looks like Wordpress is our most flexible option, but how well does WP integrate with Hybris? We don't want these sites to be completely separate, but for the content hub to sort of nestle in the webshop, whilst also being a destination in itself with its own look/design. Has anyone created a sub-site or microsite using WP on an e-commerce site that uses Hybris or another e-commerce-focused CMS? 

It looks like Hybris has a comprehensive API. And there are some developers who can do the integration for you.

What's not clear is what you want the integration to do.

If it's just to publish content you could use something like this in stead of creating a WP site: https://www.hmmh.de/en/news/hmmh-blog-extension-for-sap-hybris/
