I don’t remember navigating menus being particularly onerous.

Getting around is tedious at first, but soon you get vehicles, and, even better, this zipline thing that you can put anywhere. Those are fun to build and navigate.

The only recommended combat is tying your enemies up with ropes, or later, with a rope gun. (I wonder if Kojima is into bondage) I mean, you can kill the enemy couriers, but it’s not a good idea.
