We have two hatches forward of the mast, the lower foredeck hatch has hinges fwd, the one in the cabin top has hinges aft and acts as a ventilation scoop.
I have the same set-up: The forepeak hatch (the forepeak is isolated forward of a collision bulkhead) has the hinge forward, but has a small opening flush port set into its steel plate so you can close it but still get ventilation.
The cabin top hatches are about 18 feet back from the bow, are 19 x 19" A&Hs on four inch teak surrounds and open towards the bow with the hinge at the aft for the same reasons.
I would think the logic of one over the other would be dictated by the "offshore factor" of the boat's intended use, and the design of the foredeck regarding camber of the deck, height of the cabin house, and height of the cabin hatches, wave breakers, etc. above the cabin top.
I know that close-hauled in ten foot seas, my foredeck barely got damp, whereas we caught a fair bit of spray blown aft on to the higher, more exposed aft deck. I also noticed not a lot of spray on the pilothouse forward windows. Off the wind, we got spray only. Running, it was pretty dry. Your results might vary.
On a C&C design, by contrast, the "spoon bow" with the flush forward V-berth hatch stayed dry, but we got green water sweeps aft close-hauled in 35 knots. The seas would board at the low point in the sheer and just fly back into the cockpit on the low side. But the foredeck was merely wet, not inundated.
