Just wondering what purpose these things serve that are inserted in the shifter cables where they come off the handlebars?

In line barrel adjuster I think.

That's what I thought. I tried turning them and it didn't appear that any adjustment was being made. Do you turn the barrel or the black ends inserted into it? I think I'll leave them off when I replace the cables as they don't seem to serve a purpose for me.

They are inline barrel adjusters from Jagwire. Hold the black end and turn the barrel. I like them they let me easily adjust the derailluer cable tension when the shifting get a little off.

sometimes the ferrule slips. you sometimes have to hold the cable and rotate the barrel to get it to adjust. You can see a shiny barrel inside the textured barrel that will move in/out when you turn it.

You just need to get used to them.
