The bindings are for all on foot equipment and suits just as the ship and SRV ones are.
Well for the basics, forward and back on the throttle to move in those directions with the boost button for sprinting.
Primary trigger on the joystick to fire/use tool and the usual button on it to select things.
S to bring out the suit specific tool, pinky trigger plus space to holster the current item.
etc.
Actually the best thing to do is by going through the bindings while in a base or station and choosing the ones that you find most comfortable and intuitive set all the non combat ones, then go well outside any bases and do the same for the combat binds.
While I use the HOTAS for all three some people use different controllers for their ship SRV and on foot the important thing is that it works for you not that it is like anyone else’s setup.
