Hi, I came across this when I was looking for solutions for my non-touch bar 2017 MacBook Pro. This isn't Solus specific info but I trust that shouldn't be an issue.
I assume your model is 14,2. It looks like bluetooth can be made to work while you can have limited functionality for the touch bar. But weirdly it still has wifi as not functioning on your model, so well done on getting it to work!
Is your audio working though? Problems with audio ultimately put me off installing Solus on mine, although I've just noticed the problem with audio output is stated as being resolved for my model, so I might reconsider at some point. For now though I'm still running Solus on my much older 2011 machine.
