When I group by {Parent} it only says "CloudSec-378" and I want it to find/return the associated issue key and summary, so the grouping title is more clear ex (CloudSec-378: Ent Sec Internal Documentation)

The primary field here is the issue key. The issue key represents an “Epic” when the {parent} field is blank or when the issue type is “Epic” not “task”.

The parent field links issues, with their epics - this confuses my existing formula for concatenating parent and summary or issue key and summary fields.
