There are lots of great options for you. As Doggy mentioned lots of companies make kite specific surfboards that often have inserts in the deck so you can add straps. Some come without inserts to reduce weight slightly, but I think the strength of boards with inserts are a little higher.
We demoed the Cabrinha Skillit 5'6" thruster and S-Quad 5'7" at our shop last season. Both were great boards. They felt solid, I rode the s-quad mostly because the quad setup just seemed more fun to hack. Given your weight, you might want to stick with Doggys recommendations and keep around the 5'10-6'0 range. These models both come with optional straps but no special fin setup options. Also pretty expensive, have some eco friendly aspects to their production.
RRD makes some sweet rides too, might feel a bit heavier but they make really nice straps. I like the Maquina and the ASSO pigliatutto.
I recently picked up a Firewire Hellfire (KHF) in a 5'6". I'm only 63 kgs so if you went this route, I'd suggest the 5'10". They are discontinuing the Dominator which has more volume but would also be good if you could find one. Anyways, they make other models without inserts but the Hellfire has inserts. It's slightly heavy but feels really good. I feel like sometimes the really light boards fly away in strapless airs if you aren't paying attention. The Hellfire has 5/4/3 fin configuration and comes with 4 fins I think, or maybe you can choose thruster set up but you can change back and forth between the thruster, quad or whatever you choose as long as you have the right amount of fins. The quad setup works really well for light winds, something I like to change up and then go back onto my thruster setup for more wind. The bottom surface is also double concave which has a really nice feeling through chop and sloppy waves.
They don't come with straps or deck pads but they are sweet. I suggest going to http://www.firewiresurfboards.com/kitesurfing/

Once you get a board, spend some time in a sound, or bay, or less wavy waters to dial in your gybes and turns without the straps.
