Hi guys new here, I apologize in advance if this has been gone over several times before. OK so I am planning on running cable to a new outlet on a post about 100 feet from my main panel, I am planning on using a new 20amp breaker, I am trying to figure out what type of cable (UF or seperate strands) and how many? I have heard that UF is the cheapest way to go but I'm not sure if it will work for me, It will be under a concrete slab which is not there yet, It will be just for the receptacle for now but eventually I will have some sort of light for a basketball court and a few low wattage garden lights, and a gazebo that will need power so I want a setup that will be suitable for that in the future, let me know if there is anything I am leaving out and I will try to explain as well as possible

Thanks in advance for your help
