From my experience: while company-wide chat systems (slack and similar) help employees help each other, remote working is a lot about working on your own.
Whereas on a regular job you can walk to someone's desk or ask someone to come and help you, doing the same while working remotely is a bit harder.
So working remotely is a lot about being able to work on your own in the sense of being able to take care of things assigned to you, and figuring out how to do what you don't how how to advance.
This is to say that, in my opinion, you should choose one of the "various" things and specialize in that thing.
