Probably a topic for a different day, but it's rare to get someone's nutshell version of ethics so concise and clear. For me, my concern would be letting the evolutionary tail wag the dog, so to speak. Utility has the advantage of sustaining moral care toward people far away from you, which may not convey an obvious evolutionary advantage.

And I think the best that can be said of evolution is that it mixes moral, amoral and immoral thinking in whatever combinations it finds optimal.

… and I tend to think of it as the safest route to doing OK at consequentialism, too, myself. The point is still basically good outcomes, but it short-circuits the problems that tend to come up when one starts trying to maximize utility/good, by saying “that shit’s too complicated, just be a good person” (to oversimplify and omit the “draw the rest of the fucking owl” parts)

Like you’re probably not going to start with any halfway-mainstream virtue ethics text and find yourself pondering how much you’d have to be paid to donate enough to make it net-good to be a low-level worker at an extermination camp. No dude, don’t work at extermination camps, who cares how many mosquito nets you buy? Don’t do that.
