Two CMS's that are very good in this regard, but not open source (and not free) are:
* [Craft CMS](https://craftcms.com/ https://craftcms.com/)
* [Perch Runway](https://grabaperch.com/products/runway https://grabaperch.com/products/runway)
Both are $200~300 per site, and like ProcessWire they are completely markup-agnostic and give you total flexibility to define your fields however you like.
