> Like something I've been struggling with is how can I show effort in the design of a product if I can just one-shot it with a prompt?

You're discovering that effort doesn't matter, only results.

I bought an old house and started renovating it. Countless hours of back breaking work to get things up to a modern standard of living. Yet bringing people over to see the finished result felt so hollow. There's no "gosh this must have been so hard, great work!". To them it is just a house, like any other. The incredible amount of effort on my part to get it to that point meant absolutely nothing. No one cares how much work you put into something. It ultimately only matters what something is or isn't, and competence is the expected baseline.
