I've used a variety of battings, all with success.
For flat wall hangings with minimal quilting I've used fusible fleece. It comes in fusible on one side or fusible on both sides. I've only used the one that is fusible on one side. I iron the backing onto that side, then flip it and pin baste the top. That's an easy way to make sure you don't get any pleats in your backing fabric.
For wall hangings where I'll be doing more quilting but still want a flat look, I use cotton (either Warm and Natural or Quilter's Dream), Hobbs 60/40 blend of cotton and poly, or bamboo.
If I'm looking to showcase the quilting and want some areas to stand out, I use a double batting, either cotton, Hobbs 60/40 or bamboo on the bottom and then wool on top.
