It looks[1] like you can use Cert Manager with CloudFront[2], but not directly with S3.
CloudFront is very cheap[3], but it is not free. (For that matter, S3 itself is cheap but not free.) It's therefore a solution to “I'm employed in a developed nation and don't want to notice that I'm paying for hosting”, but not to “I have literally no money to spare for hosting because a year is less than coffee” or “I want my content to stay up without my having to remember to keep a valid credit card on file somewhere”.
[2] CloudFront ≠ CloudFlare. Nobody in this thread has been confused about this, but it tends to trip people up.
[3] I ran tech ops for a company whose site was, on launch day, around the 55th-most-popular site on the internet. I think our CloudFront bill was $300 for that day.
