Path to Glory lists

So me and my friends have decided to play a Path to Glory campaign as a way of coming back into the game and painting our minis. I haven't played AoS since second edition (except for a few Spearhead games), but I have most of the new models.

We have decided to start at 700 points, but it's been so long since I made a list that I don't know what's useful and not anymore. What should I include?

Thanks in advance!
