I do very limited wildlife, but are many critters going to be out and about in January?
Spruce Grouse, Hares, Northern Hawk Owls, Pine Martens, Chickarees, Elk, Bighorns, Dusky Grouse, Ptarmigan, etc. Lots of winter residents that will be "out and about" ...... but you do have to go looking for them.

If you expect to see something, I suppose the 100-400 would be the choice . . .
Yes, the 100-400mm would be the best choice for the winter residents, with the possible exception of the Elk and Bighorns, which can sometimes be effectively photographed with the 70-200mm focal lengths.

For what it is worth: enjoying time with wife, IMHO, is incompatible with serious shooting. Your mileage may vary

Very true. Serious shooting means that if you find a good Elk, you stay with it for hours, waiting for it to present the very best opportunity with respect to backgrounds, light, etc. Same with any other animal or bird, no matter how big or how small it is. You find something you want to shoot, you then stick with it all day if you're able to.
Same with landscapes - you find a point of view that you really like, you stay there for hours, or keep returning to it over and over again, in order to get it when the light is just right.
I know from experience that wives may tolerate this serious photography, but they don't like it.

"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".
