When doing major outlays like that you want to use an underground conduit that allows changing of the medium at a later date. There are many options and the conduit looks like orange PVC for your house but often has an embedded copper wire for toning the location. What ever technology you chose, just beware of how the NEC refers to "Structure to Structure Wiring" because Fiber Optics often have a Stainless Steal strengthening layer that can be, on accident grounded to both ends of the connection.
There are some vendors that will sell the complete assembly for less money.. The conduit in roll form, filled with you mix of twisted pair, fiber and even water table pressure tube*. I could write a book about media converters and compatibly. Look for a slot load rack mount fiber transceiver system and use redundant links on a bond. * Water table pressure tube is a method of keeping the conduit dry by applying 5psi of air to the tube to push water out. Its very standard.
