I could see the #4s being a reasonable choice IF it were actually #4Buck. NOT #4 bird shot.
Personally, my choice among the listed options would be the 12 gage as well. I would go with a solid slug, not a hollow base like so many that are available for hunting deer with. With a slug of that diameter, you need more penetration than expansion. Cast your own slugs out of wheelweights and have a couple percent by content of zinc in there to really harden it up and you should have great penetration and very little expansion. Put it in decent wad and it will never make contact with your barrel, so leading won't be an issue (not that it would be in this kind of a situation).
At short distances, I would also want a short barrel for handling. If the bear gets on top of you (or even very close), a long barrel is going to be very detrimental.
And, FWIW, a .270WSM loaded with proper ammo should still be able to put down a big grizz. After all, how many grizz have been killed by the lowly .30-30 and the shooter lived to tell about it? Would it be my top choice of weapon? No, but it is better than being dinner.
