I'm actually working on a book which I think covers a lot of what you're looking for (and was what I wanted back when I got started with Elixir a few years ago). I'm covering architectural patterns for the items you mentioned as well as flow control and digging in deep on how to really leverage the fault isolation mechanisms of OTP. I'm the maintainer of Distillery, the release tooling in Elixir, so I'm also covering a lot of the gritty details involved there, such as how to work with hot upgrades and such, as well as dealing with issues in production using some of the excellent operational tooling available. Unfortunately I probably won't be done until the end of this month, but if you're interested, keep an eye out on ElixirForum.com, since I'll announce it there when it's available.
