Your end goal focus is fine and I'm glad it improves your quality of life. Same here whether I focus on edibles or natives in my own garden. But I'd caution you about the "throw random seeds" approach, unless you've sourced those seeds and aren't using retail seed package "for pollinators". Those are notorious for frequently including invasive species.

A few examples among many similar studies:

"See what sticks" is inherently biased toward fast spreaders that will outcompete and outspread other plants regardless of their ecosystem services. Even if they're natives.

But like the parent comment, I can't tell you that your own enjoyment isn't warranted in your own garden. The whole point of Indigene is to try and contribute to tilting the balance a bit more into being more aware and focused on the ecosystem benefits of what you plant or don't plant.
