[oc] use-package config question

[Bruce D'Arcus]

As I'm trying to put together a PR for the doom module for adding
org-cite support [1], I'm realizing I really don't understand
use-package very well.

Could someone with some expertise in this area recommend how I do the following?

Load org-cite and it's associated packages (oc-basic, oc-natbib,
etc.), and set some associated variables, if org-cite is available.
