I can't get the Internet <-> CloudFront <-> S3 Bucket working, using an AWS certificate. This is what I did:
*.mydomain.example
.After the distribution is created, my browsers all tell me this:
I'm not sure if I've missed a step in the process of setting this up, I've tried fiddling with various parameters but nothing lets me through.
I read this blog post, saying that I might have forgotten adding alternate CNAMEs. This confuses me a bit, should I? In Route 53 I configured my full domain using something.mydomain.example
and the certificate is a wildcard one.
Other blog posts and question answers indicates I should not, just use the A record and the CloudFront distribution URL/endpoint, as I have done.

So, in my update, I mentioned adding CNAMEs from a blog post. This was it, the second I did that, it started working.
To clarify, I did this to solve my problem:
something.mydomain.example
that you have configured to this distribution's endpoint/URL in Route53.This solved it instantly for me, but remember that CloudFront configuration changes sometimes can take some time to be pushed out.

Weird but true:
What actually fixed the issue for me was bumping the minimum cypher version up from TLSv1
to TLSv1.1_2016
in the CF Distribution.
Here's the relevant CloudFormation snippet:
HttpVersion: "http2"
ViewerCertificate:
AcmCertificateArn: !Ref SslCertificateArn
MinimumProtocolVersion: "TLSv1.1_2016"
SslSupportMethod: sni-only
Weird because I don't understand why this change fixes anything. The browser should automatically negotiate the higher TLS version.

As stated by OP in an edit error caused when a CNAME entry for the apex (naked) domain, www
subdomain, other subdomain or other domain(s) are not listed in the distribution.
To fix add at least one CNAME to the distribution in CloudFront.
