Cat5e would do fine. But in my opinion Cat6 is the future. If you want to future proof you can also use Cat6. Main difference is speed and interference. I think Cat6 would be costlier than Cat5e.
Look at here: http://www.diffen.com/difference/Cat5e_vs_Cat6
But you can use any depending on what your main concern is speed or cost and both would work with data and voice and provide poe as well.
