However before the user can enter their response on the console the graphic display starts up.  In the unit file I've tried all sorts of combinations of Requires, After, WantedBy, RequiredBy, etc. to make the graphical.target happen only after this script has completed its execution to no avail.

Delaying graphical.target won't delay start of display manager.
graphical.target already is ordered after display manager, delaying it
further won't change anything.

You need to delay actual service that starts graphical environment,
display-manager.service or similar; which one depends on your distribution.

At least if I understand your question correctly.
