The video below explains how to caulk cracks in stucco walls, whether structural or small.

As far as gouging, as long as the inside of the crack is clean, say you pressured washed the walls or used a wire brush, this etches the inside of the crack where the caulking goes, your good.
However, I’m scraping where the two cracks meet as this was like an earthquake; it caused both sides to flair out words, so I had to scrape that hump or ridge off; while I was doing it, I gauged or cleaned the sides as it had dust dirt grime and other junk in it.
Remember, nothing sticks to that stuff, not even the best caulkings.
Okay, spider webs stick.

What happens if the crack is deeper than 3/8 or wider than 3/8, and you caulk it, and over the next few days, you notice the caulking got sucked in? Nothing happens.
You add more when you have time. In this video, I smeared the caulking, as that needed to be done.

As a rule, you fill the crack any gets on the existing wall with no problem, feather or blend it in.
Thus when painted, it won’t show.
Now you know.

Yes, adding sand will match the stucco finish, and no caulking is stronger than Sikaflex 1A caulking.
Structural cracks in stucco walls occur with the settling of the home.
If these cracks are kept caulked, that will protect the membrane and the wood substrate.
The drag is knowing this and doing it.
