I was thinking about a fatbike as well, and so far I’m holding off. I really don’t want another bike. Below is what I’ve kind of decided...

My gravel/bikepacking rig has 27.5x2.1 tires. I may buy tires with more aggressive, wider spaced knobs just for winter though. I don’t commute; it would be for riding those same gravel roads after it’s snowed, and the snow has been compacted somewhat. Studs would be nice for the odd ice patch, but as I won’t be doing this often I think I just need tires as mentioned above.
