Can anyone recommend good resources for learning how to design NoSQL (document) data models?

I'm interested in stuff that talks about how to make the choices about distributing data across collections, etc.

When to have a single collection, when to split data across different collections, when to duplication data, etc,

Mongo db creators have free online courses. M101 for language specific and M102 for DBAs. I had done both of them sometime back. And they would answer most of your queries.

True these courses are mongo specific, but still they cover a lot about NoSql and distributed databases, scaling up etc. Here's the link.

Happy learning

@gymmerDeveloper also this is related only to document specific storage i.e. document oriented nosql dbs. There are other types of nosql dbs which you'd need to search for. Just clarifying.
