I wouldn't angst over it too much. If you're gonna be shooting store bought ammo, just get a 30-06 and be done with it. Rem makes them with any stock you could want on them. And they load factory ammo all the way from 120gr bullets up to 220gr bullets. And the ammo is available everywhere. You will hear all sorts of esoteric suggestions but for a first rifle remember this, the 30-06 is the old gal that puts supper on the table. Every day; anywhere.
I would go at it a little differently than you however. I would get the rifle in a CDL model (for looks) and buy a medium (or less) priced aftermarket synthetic stock for field work or bad weather. Its just that taking a plastic contrivance out of the gun safe and rubbing a tack rag over it doesn't ring my bell like a nice wood stock does.
One point: regardless of what you end up with, when you buy your hunting ammo, get several boxes FROM THE SAME LOT. Different brands will shoot to different points and you will find variations from lot to lot even with the same brand.
And finally, when you get into reloading, the 30-06 is an easy cartridge to reload with a wide range of components available.
