Julia, Clojure and Go. Are any of these good for a beginner or should I start with something else?

That totally depends on what you want to do.

Go should be easiest since it's purposefully simplified in order to make learning it easier. There are some more difficult concepts, but the start should be easy enough. I know about go with tests, but it's not really programming beginner friendly.

I'd avoid clojure as a beginner. It's more for people who know java, but don't want to write java. Common lisp and schemes are good for learning programming, but they're not a popular group of languages and that can be a problem.
