The one thing
The choice that moves your numbers most is simply how much fat (whole/2%/skim). And one safety point: lactose-free is NOT dairy-free.

The honest bottom line
For nutrition, fat level (whole/2%/skim) matters most; ultrafiltered adds protein; grass-fed/organic are a small omega-3 bump and mostly farming.
For digestion, lactose-free (or A2) can help.
⚠️ Milk allergy: lactose-free, A2, and ultrafiltered are ALL still dairy — you need a genuinely dairy-free product (oat/soy/almond), and always check the label.
Something interesting
"Lactose-free" and "dairy-free" get mixed up constantly — one removes the sugar, the other removes the milk. The single most useful distinction on the dairy aisle.
