I just use pass[0]. I namespace all my "passwords" with either "web/" "contact/", "local/" etc depending on what it is.

So contacts are my address book.

  pass edit contact/john.smith

And the contents are just toml files, eg

  name = "John Smith"
  email = "john@example.com"

  pass show contact/john.smith | toml2json | jq '.email'

Edit: I also wrote a little script that will crawl the contacts and build out a vCard for phones, email, etc. This works for me.
