I've run high scale, high availability Go clusters involving thousands of nodes, dozens of eng teams, and it leveraged k8s. I've also worked at an Elixer shop with a few dozen engineers at a low scale ecommerce solution. The Go system was doing around 100k api calls a second, the Elixir system peaked at about 3k rps. I would choose Go every single time. It has a better story for teams working together, largely due to better typing. Lacking types (and specs don't cut it), I still found I had to go up multiple function calls to understand what the parameters were, how they could be used, etc. so much state has to stay in your head, which I did not expect from a functional language
