This is precisely why netlify's offering is valuable. It works out of the box with zero config. If you're using a common static site generator you don't even need to setup the build process, just give it your git repo, and push when you want to deploy.
That's not really a compelling reason when it's literally a single input field on a form to setup. Also, if you're in the business of web development, HTTP cache control headers are something you should know about regardless.
As with a lot of AWS, it's easy if you know you need to do it, but there are a lot of gotchas which can be very expensive if hit (and there's no way to limit expenditure).
