for Amazon S3 i setup the s3, cloudfront & cert manually (should put it in terraform, but it takes just a second). here's a nice article to walk you through that (says it's for hugo, but you could use it for any ssg): https://agop.me/post/https-enabled-portfolio-hugo-s3-cloudfr...

then i build and deploy with a bash tool i made called NanoCD: https://github.com/tkjef/NanoCD

has lots of helpful options. easy to wrap your head around. easy to add whatever workflows,tests you'd like.
