Check out the CZ bolts too, especially for a classic mauser well made. Seemed to me that the 223 mini mauser I had briefly was just plain right in all aspects without any little shortcuts others take. And I've heard the action top is cut properly to take the Rem 700 rings. Some of the models may be stained but not have the finish so you can make small modifications to make it right for you, a plus to me. Also they offer 3 lines, American stock, European stock and Mannlicher full stock. And it has a decent trigger and a push forward to set single hair trigger.
Savage, or Browning with the boss may be the most accurate, Remington also, if you want a push feed. Winchester Classics have the controlled feed, as do the later Rugers. CZ's likewise have decent reps for accuracy. Without a scope and with the wide range of factory ammo, to two hundred yards I doubt practical differences will be noticeable. Far as power, Hornady and Federal have light magnums in both calibers ( 308 and 30-06 ). The 308 tends to be more developed as a match round, the ought six, more powerful especially at the heaviest weights.
In your situation I'd grab the CZ with full ( mannlicher ) stock, mount a peep sight on top and a low power removable side mount scope for sighting and go for it. Get the 30-06 if you can get it without excessive trouble. 308 would do if it's too much hassle. ( I'd grab me a 7x57 cause of arthritis in my neck. The 30-06 gives me next to a migraine cause of that. Same with lightweight 308's. But that's me. )
You've got several months to make up your mind or get it like you want. Stretch the fun part of a new gun just right as long as you can. And have fun
