That's pretty close to what Netlify is doing behind the scenes, isn't it? Why would configuring it yourself be better? Netlify has way more experience at that than most people.
I haven't used Netlify since I've been using Cloudfront since the day it launched many years ago. They give me free SSL, charge me like a dollar for it and have been ultra reliable forever.
I'm quite happy with other AWS architecutre also, e.g. SES for sending mail, lambda for serverless, etc so I like to stick with them. Awscli is also quite powerful and I'm able to setup the whole thing from scratch with a single bash script.
I'm sure Netlify must have simplified the process or made it easier and could be another great option.
Netlify likes to go down unless you are paying for the high tier. Also they charge for bandwidth after 100gb's ($20 for another 100gb's which is basically stealing money compare to how much a 100gbs is worth).
I would not recommend Netlify if you have other options.
