E. g. it's a basic functionality deep in the game engine that units in a hex stop movement if it's not possible to move around. Only air units can avoid that because they move directly to the target hex. If we do this with naval units then hidden subs can't intercept them and you don't see the movement path of the naval units.

Since ground and naval units have to move from hex to hex it means that they need a path of empty hexes or friendly hexes to reach their destination hexes. If a sub can block naval movements it's the same as surface ships can block the same movement. The difference is that with the surface ships you can instead attack the blocking units. With subs you will have them dive before you inflict any casualties. It's similar to the naval units arriving a bit too late to actually harm the subs. But you initiated a search for the subs and thus stopped moving on.

I think we can find many situations where the GS game engine doesn't simulate the real war accurately. A game can never do that. What's important is that the game is playable and fun. Trying to fix what you describe can introduce a lot of undesired situations and I don't see this as a big problem. There aren't many chokepoints on the map. A sub can always be attacked the turn after if they decide to remain in the hex to block further movement.
