We were thinking of using the sensors for guiding our robot during the autonomous period, and need them to be able to detect surfaces at approximately 3/4 meters away. What type/brand of sensor do you recommend that we buy? Which are compatible with the NI roboRio? Any help is appreciated, and thanks in advance!

Our team happens to have a fleet (literally) of HC-SR04 ultrasonic sensors. They're extremely cheap, have built-in software support in wpilib, and we have tested them to measure accurately from about 5 cm to several meters away. This will be our first year using them in an FRC robot, but we've used them in smaller robot projects.
