I have some doubts and some of your comments are in the same line:
- I only windfoil in light winds (10-15knots). A long board is better to take off in those conditions. Would a fat tail and short specif foil board take off earlier?
- Longer board easier on breaching and uphauling than a short specific one?
- My board with tracks weigh less than 9 kg. To get the same weight in a wind/wingfoiling board you have to pay for carbon
Only clear advantage of short board is manoeuvrability, high winds and winging
Any other advantages of foil specific boards regarding foil-board balance or jibes?
Foil specific boards do help early takeoff with proper pumping technique, which does take a while to coordinate and push the lower limit on.
I'm not convinced it's board length that matters for breaching as much as shape but I could be wrong. I've yet to have a serious breach that catapulted me on my shorter foilx. If the board has a chopped nose like the wizard 114 it is hard to uphaul but the foilx 145 has lots of volume in the nose. So it depends on what board.

I remember seeing videos with guys saying that slalom boards (used for foiling) have more swing weight than a short foil board, and they made it sound bad! But the more momentum you have going through the gybe the better, and the larger surface area increases the same ground effect that a pelican experiences when gliding close to the surface of the water. Of course you have to also keep the board close to the surface of the water to experience the ground effect.
You want speed in the jibe. Flying board=drag and windage loss. Board lift is constrained by the angle of the foil and is going to be negative when going upwind when the board nose is pushed down from being tilted with counterheel. You can feel the difference in different boards with how they react in gusts. Even between the Blast 145 and foilx 145 i felt a big difference in the nose with windage (and mast track position). They are 6cm in width apart but the foilx is much shorter.
Honestly Mucel if you can borrow a windfoil specific board to play around a bit it would be best before you decide.
