I have a pretty interesting scenario I need help with. I need to run a cable underground for approximately 700 feet that will have to be cat5,5e, or 6 and have a switch connected at both ends. I cannot put a repeater in the middle of the cable due to it being located underground. A non-mission critical device will be connected on the furthest end.

Use fiber optic cable and put media converters on each end to convert to ethernet.

The max run for Cat 5 is about 100m = 300ft.  I know that Cat 5e and STP Cat 6 can run a little further, but most show total signal loss at about 400ft.  If there is absolutely no interference, maybe 420ft.  Anything over that is just not possible without a repeater of some sort.  Your only option is fiber or some sort of wireless network if you have a clear line of sight.  However, 700ft is pushing for even the best wireless networks with a clear line of sight.

Wireless will work fine if you use good quality antennas and mount them on the outside of the buildings.  You can go miles wireless with good equipment and line of sight.

The wireless is probably your answer.  I'm not at all familiar with high-end exterior wireless equipment, but the Cat 5, 5e, or 6  is out of the question.
