OP, I believe your idea about the .243 fitting between the .223 and the .308 is correct. The .243 has lots going for it. Its accurate and mild mannered, there's a great selection of components for it, and its deadly on game up to 100 pounds or so.
But, IMHO folks get a little carried with their enthusiasm for the .243 as a big game cartridge. While it can perform well on caribou (which give up easier than their bulk might suggest), small deer, wolves, and antelope, it lacks the bullet weight necessary to meet the requirements of a general purpose big game cartridge, which in the North American context includes moose, elk, and large bears. I bet if you name any cartridge you’ll find someone who has killed some big critter with something smaller; even if doing so doesn’t make it wise.
As for concerns about barrel life, in terms of a hunting rifle, you can set those aside. Competition shooters get nervous when their rifles won’t hold a quarter minute, but that level of accuracy can’t be exploited in the field over normal ranges. How much you shoot a rifle determines how long it will keep its edge, but even with frequent use its hard to imagine that you wouldn’t get many years out of your .243 barrel before it wouldn’t hold 2 MOA.

The .243 has its niche and performs exceedingly well within that niche. Its performance outside that niche is on a sliding downward scale as game weight increases, although it gets a bump if the shooter chooses a premium bullet. But IMHO, if your only viable shot is a head shot or to slip one in between the ribs, hoping not to hit a bone, then you need to use more gun.
