Roast and steak are about the same for the desired temperature/doneness. Remember that you have to be at least 132 degrees for the fat to render. I have done lots of sous vide, settled on 135 for steak, and then either a hot pan sear, a torch, or bbq finish to char the edges and surfaces. I would not do the 3 minute sear or 3 minute bbq finish as suggested, as it will cook the meat more. Your personal preference on doneness and sear time/method may vary, but like anything, eventually you will make it your own and folks will be asking you how.
Reverse sear also works, I do it for Beef Wellington in sous vide method.
