First, if you want to be a military pilot apply for ALL of them, including CG and Army. Also, apply for as many AG/Reserve units as you can. Don't worry too much about where they are or what they fly until you get some offers.
Don't sweat helo's in the AF/Navy because you will still go through fixed wing UPT which opens up opportunities later. I know a ton of Helo guys who later got a fixed wing gig(to get those hours) and loved flying the helo's while they did.
As far as my opinion on order of preference (once you get all those offers):
1. AG/Reserve (Heavy, prop, fighter, helo in that order)
2. AF (same aircraft preference as above)
3. Navy
4. CG
5. Army

Lastly, whichever route you take, ENJOY it and don't worry about what could have been. Make the best of it and always be networking (maintain all those connections, thank you FB!) and planning for the future whether you go for 20 or just the committment.

Full disclosure I'm a former AD AF C-130 guy, now Navy Selres UPT IP.
