I've seen them channel the insulation, but this is a bit more lazy of a method. This is an exterior CMU wall in climate zone 1A.

I have noticed in your pictures of plumbing that the hot pipe is not insulated.

California doesn't have a section R403.5.3 but California has the same rule somewhere else.

Rembo, what do the plans require ?.........If the sheet type
insulation is what is required, then have the plbg. contractor
remove their piping, have the full, "non-hacked up" sheet
of insulation applied to all areas of the wall, then have
the plbg. contractor to install their piping in a compliant,
"non-lazy manner", and then have another inspection
performed to verify the re-do.

There is no room behind the drywall for insulation and the pipe.

The furring strips could be notched if done properly,
by someone who actually cares about the work \ project.
Then install nail guards over the notched areas.
Not the typical "wood butchering" plumbers.

Is the Insulation require? In a 1A would it need to be there or is the block it's self sufficient?

Exactly. That little bit of missing styrofoam can’t be a real problem.

I have encountered a heating issue with pipe in attics and on the exterior of the building. It can be significant. In your case the furred walls limit your choices. A thermal break might help. What do they do to mitigate the problem?
If the CMU gets that hot why is there not a better insulation method?

When I lived down there my dad moved the electric water heater to the attic to save on electricity.

Hurricanes, alligators, pythons, bugs the size of dinner plates, more lightning strikes than anywhere else on Earth and now this…. The average Florida H/O insurance policy is $6000 for a reason.
