If you don't have respect for CRUD apps, why are you trying to get a job doing CRUD apps?
Another reason is that I'm a digital creator at heart, not a programmer. Ultimately, I don't care about programming, I care about putting whatever is in my mind into the real world (despite that I did my best to learn CS as I did find it a valuable form of knowledge). And I find programming to be the most effective way to do that. I think creating CRUD apps is quite close to digital creation.
It's less of a headache (compared to other types of programming) and more visual (if you're full-stack or frontend).
Focusing on this and working "value creation" in to it will come across a lot better than anything that could be interpreted as "CRUD apps are easy and I'm looking to bludge for a while before I bail to something challenging again".
