How big are you and how windy is it?
Assuming you are not a giant, that board should be good. More volume is your friend when starting....that board is about same size as armstrong 6.6, which is 130L. If you're already a proficient sup foiler, you'll find that plenty stable. You can consider downsizing later, but you can also ride that well into intermediate.
When starting out, more wind power helps. Power on demand and something to lean against. Later on when you get more efficient you can generate power from pumping and need less wing. 6m and 7m wings are optimal for 10-18kt ish. You'll find that you dip your wingtips starting out, but you get used to that quick. More windy, smaller wings.
Play with wing on land, learn where the power is, how to release power. Run back and forth across the wind, practice turning down wind ... where does the wing go, where do your hands go, it's a dance.
On board on water, turn wing over into proper position and hold with front hand (do it before you get on board). Get on board on your knees. Get wing in flying position, get a little forward speed then stand up in surf stance. Wing at 45 degree angle, not in front like a windsurf sail, not overhead.
First time on board you'll probably end up downwind, plan for it and don't be disappointed. Without getting on foil, you can focus on body position and wing position to point across the wind and even a little upwind -- slogging.
To get up on foil, you'll feel the board accelerating. Just like sup foil, you'll feel that moment where it wants to lift, a little ollie and up it goes. If wind is light, then you pump the wing up and down to gain forward momentum. It is more up/down, like doing chin ups, than it is a move forward. As you feel some speed, you also pump on board/foil, the 2 pumps go together to get the board out of the water. Once it is free, you need way less wind power.
First turns are far away, but it may be easier than you think: in your dominant surf stance, with wing overhead and no power, bear off downwind, just foiling along all quiet and easy. And then you'll get bored, so just do a slight turn to toeside, engage the wing to get a little power (it'll feel all twisted and weird). Then turn back downwind and then turn to your regular stance again....and that's a heel to toeside to heelside s-turn, the basic functional move for wave riding! And so it begins.
