Soil is sandy loam.

For me frost depth is 3 feet, my porch has been fine 35 years set at
ground level on block, a 25 x 30 foot deck, so to just say below frost
line is BS

To me, a deck is not a porch. You can attach a deck so it slops up
and down with the frost. [I wouldn't- but you could] A porch
needs to be rigid so the roof doesn't rip away from the side of the
house.
If it is on bedrock, there isn't any frost heave, so you can get away
with more.
But if it was mine, I'd go below frost and not have to revisit that
job. On sandy loam I'd also want a huge elephant foot set on
compacted crushed stone.
But that's just me. If there will be a permit involved, the only
person that can answer the OPs question is the OPs building inspector.

At least 4 feet. Use Sonotube's BigFoot base if possible. At a minimum
wrap the Sonotube in polyethylene to help keeping it in place in the
face of frost heaves. Most decks don't weigh enough to keep a straight
footing in the ground when there are frequent freeze/melt cycles.

Sonotubes, yea right, bs , if he is building an addition ok, but this
is a dam Deck, nothing more. Even small sheds you buy are recomended
to have Pads, not foundations to frost. A fence yes, but not a deck.
