Any of the first three choices are plenty good enough. I'm not a magnum rifle fan by any means, the ammo costs are considerably higher than "normal" stuff, and that is a factor for you. The WSMs won't die out, but the ammo costs more, kicks more, and doesn't kill any deader than the others.
Since you've got a youngster, I'd pick the .260, just for his sake. It doesn't kick much harder than the .243, but kills a lot better. I think, as time goes by, it will become a lot more popular than it currently is.
The .280 is a good choice, but ammo selection is poor enough. It's been around for a long time, and ammo selection has never been very good.
