The best case for drop in companionway boards is strength. If you have doors hinged on the side with a centre line join that is an inherent weakness I'd have thought. Boards are also easy to stow completely out of the way.
For screens I'd adopt the old build a timber or aluminium frame with insect screen to use at anchor. If the frame is reinforced with a steel frame and lockable from the inside you solve both the security and bug problems in one hit although I acknowledge access is still an issue.
Maybe someone has a decent system of doors ? If so I'd like to see it also.
