Recommendations for wire

1st since this is my 1st post let me say hello. I might have years of experience with distillery equipment but I’m very new to RGB lighting.
I have a 12’ x 12’ gazebo located on our attached deck that I want to plan a lighting project for. I plan on having the controller and power supply located inside to house and so my question is this what type of wire AWG and number of conductors should I use for a 12v system powering a Digiquad controller? The gazebo is located roughly 10 feet away from where I want to house the controller and power supply. ANy suggestions are appreciated. Thanks for your help.
