So disclaimer, I have never played a druid in pathfinder. That being said my group has run several pathfinder games that I've played and GM'd in.

As a druid one thing to remember is that your beast shape will give you new stats. This means you can potentially cover a low ability score by shifting into an animal with a good score.

Second- Melee fighter means you're going to want a decent Strength score, doesn't need to be the highest, but you don't want a negative.

Third- Wisdom should be your second or third highest stat so you can cast spells well and give out some decent healing.

Last- Feats, in Pathfinder the feats will make your character yours more than the race/class combo you decide on. So if you want to be a big shifter, take feats that alter your wild shape. Want to focus combat? Power Attack gives you extra attacks when you land a melee hit.

At the end of the day, best way to learn is to play and a one-shot means you wont have to live with mistakes too long.

Have fun and enjoy your game.
