Use whatever you feel most effective in. I would say Ruby is around much more than you might expect by the sounds of it. (The usual big names touted on the Rails homepage + many start ups + agency products) though it's definitely over the hype period. For being employable... I'd say Ruby is going to be near the middle of the pack. Elixir is going to be near the harder-side, and JS is going to be near the easier-side... on average IMO. If you think ruby intrigues you, give it a try! You've got precious time + motivation for this sort of thing, but messing around with a programming language is not much effort if you're intrigued. Getting a feel for it is a sub-weekend project away. It's my favourite language for bodging, the scripts I make in ruby for little data-mashing or system things are surprisingly stable and readable, even a year or two later. (Compared to a nodejs, perl or shell script... which all tend to have understandability-half-lives of a month for me haha) Automate something you find annoying.
