You can use a recessed hatch pull so that everything is essentially flush.

Soss hinges will now work over time due to frame movement, expansion and contraction. Some type of piano hinge attached on the hidden section along the face of the joist or deck board will work.

How about no hinge, and just sit the hatch there in a well created by framing. Not worries about it binding from wood movement? Easy?

I suppose if the first floor were on fire and I was in the basement sleeping - but the only thing down there is my office and the laundry room so... The hatch will allow an emergency exit.

Just devils' advocate here so, ice on the steps in winter?

How about no hinges.
Where is the thing going to go?

It's obviously not as simple as cutting a hole in the deck after it's built. It must be solid to walk on so it needs to be figured into the framing and foundation plan of the future deck. Flush to walk on? More framing to support the hatch from inside the basement. Water tight? Yes, the hatch leads into the house. The surest way to make it water and bug tight is a framed hatch that over hangs a curb and weather stripped. The basement curb needs to be constructed after the deck top elevation is established. The deck boards need to be fastened firmly to the hatch so plywood, water proof membrane and flashing first. The last thing involved is cutting the hatch opening. Then it can be hinged and hatch handle installed. The hatch will be quite heavy by then and need lifting assistance. There are several ways to flush hinge it, that's the easy part
