If you use Let's Encrypt, or any public CA, all of your domains and certificates will be public. You can use a wildcard to avoid revealing subdomains. There is a website that you can use to search what is available, but I don't remember what it is.
I suspect there aren't any serious risks to having that information revealed. The only real reason would be privacy against which services you are using on that domain.
