I've heard good things about https://bunny.net/

AWS Cloudfront + S3 is basically free for tiny sites. I have a Terraform module to spin everything up easily.

Same, I’d rather not use them but there’s really not much else out there that can offer what Cloudflare does for the price (free). In particular I love the free egress from backblaze.

I’d gladly jump ship if there was a competent competitor, even if paid… within reason.
