I haven't built a full CRUD app myself, mostly some small hacked together tools and various silly stuff. Personally though I did end up just experimenting with basic stuff to get familiar with the language and tools for a couple of evenings before I got anything even half-useful done.

So I'd say, if just want to get a simple CRUD API app out quickly, use Python and Flask or something similar as it's something you already know well. If you wanna use the CRUD API app as an excuse to play with new languages and technologies which will hopefully lead to a expanded skill-set, then go for Go ;)

As for Node.js, if you already know Javascript, it'll fall about 30-40% of the way between using Python that you know and Go that you don't know.
