Do you by chance have a SID foot for your machine? I have one for mine and it makes quite the difference. It actually has a guide down the center of the foot - looks a bit like a plough that runs down the seam.

Another suggestion for a better SID is pressing the seams on the back to one side. That is easier said than done though.

As for the cotton thread - it is my preferred thread. I acknowledge that I am far from perfect, so if the thread shows - it shows. I don't mind.

Variegated thread comes in many different color lines. If my quilt has lots of red in it, I pick a variegated that includes lots of red. I generally look at the colors in my quilt and pick a spool that has those colors in it.

The big deal for me was to give myself permission to just go for it and sew with cotton thread - EVEN IF the thread was slightly off the ditch.
