Is there an easy way to kill all checked items in all checklists from a .org file? Similar to "clear completed tasks" in Google Tasks. Also it would be handy to know how to kill or archive all DONE items at once, and not per item.
I don't believe that checkboxes can be cleared or archived by default in Org. They are seen as lightweight tasks so more for subdividing tasks into smaller pieces or to create a shopping list 1 . They also do not show up in global TODO lists or Agenda views, so there is much less tracking of them.

Then mark the desired entries (or mark them all) and use bulk archive
