Ooh... so many choices.

I like Sauromatia. Good cavalry, good archers, decent infantry and nice magic. I think they are quite easy to get a feel for, plus they are very interesting I think.

The military side of things should be fairly intuitive I think. Experiment with positioning your units on the battlefield and getting them working well together.

For the magic, I'd recommend researching up Evocation. Nether bolt is very nice, and all your Enaries can cast it. If you can get up to Shadow Blast and have some gems spare to cast it, that can be devastating.
