Welcome to engineering. Pick one and finish the project. Then look back.

Yes, running an RPi Zero to watch a button press is overkill. So what? It optimizes delivery time over efficiency. You can optimize for cost or power later if you feel like it.

Anyhow, nice job.

You know what? That's totally ok. When I first heard of the raspi platform that was what I found most exciting. It was going to take a whole world of people with common web dev skills and kick the door open for them to get into hardware. I'm glad to see that's it's completely living up to that promise.
