It's just a test image that exercises various aspects of printing.
You've got some technical features (stepped and continuous grey
wedge, and rainbow), lots of grey with smooth gradations to check
grey balance, black density, color banding, you have skin tones
to check, blue sky, and a range of other colors.

Grey wedges you look for smoothness, proportionality and range.


In any case, I am not asking anyone to diagnose/fix what is wrong with
my setup.  I am just asking what techniques/tools I can use to do that
myself.


It's multi-faceted when you have the scope to tweak the printer.
One could make a several day course/tutorial out of the whole
topic, and still only form an introduction.


use to improve the profile.  As I said previously,  I can probably proceed by
fiddling with gutenprint settings,  but it makes more sense to improve the
profile.


As I said previously, they are not interchangeable. The profile can only
profile what the printer does, it can't fix things that you should fix
by making the printer behave better. In particular, Argyll is not setup
to be a "tweak" tool, it's meant to make the best of what the device does,
and be good at mapping from one colorspace to another.
