If it’s meant for daily use, then all of the coldness will just fall out when a door is opened anyways. Drawer and chest freezers are advantageous in this respect. This is also why fridges have drawers. I’ll bet you more doors has a negligible effect on energy efficiency…
as for long-term storage, this nerd has something to say about that
how does two doors make it less space efficient
if anything, the freezer is more space efficient since there’s no drawer to take up space
More doors = more gaskets = more seams = more heat loss = less energy efficent
