The closest attempt at creating a directory of standard platform-agnostic UI templates I could find is this repository [0] associated with the Adaptive Cards project [1]. Unfortunately, it only contains a handful of templates.
In practice, Google's Rich Results [2] seem to provide the most extensive set of templates aligned with Schema.org, but documentation is limited and they're not open source. Similarly, Wikipedia features thousands of high-quality infobox templates [3], but they're not readily usable outside of Wikipedia and might have limited utility in non-encyclopedic contexts.
