How can I search for or report on contacts based on date, method and/or status of group subscription?

With GDPR coming down the track I'm keen to dig in to my contact lists in more detail. I'm looking the ability, ideally through the UI, of reporting on, and searching for, contacts based on the date they subscribed to a given group, the method by which they were added to the group, and the status of their group membership.
