It is more common in certain areas than you think. For example norther part of the republic. For example, my dad is from Quba, Azerbaijan, and he has blond hair + green eyes.
The issue is that Azerbaijanis are much more heterogenous than those populations you named. There are plenty of people with light complexions, but it tends regional. Like in the North Azerbaijan, Derbent, but also sometimes can be found in Armenian and North Western Azeris.
I won't share pictures of my personal friends, but I can give you the following examples off the top of my head on the spot:
