Is my fork suitable for my wheel
I don't read French, but it is clear that the Mavic Aksium wheel you linked to has thru axle fittings: it stated that it took a 12x100mm front axle and a 12x142mm rear.
The Surly Straggler fork you linked to is for quick releases only. I believe this line:

Système d'axe : réglage rapide (9 x 100 mm)

Was saying that the fork used quick releases. For sure, 9x100mm refers to quick releases. There are no thru axles with 9mm diameter. Also, the dropouts in the fork have openings at the bottom, to let you drop a quick release wheel out. TAs need to screw into a hole on one side of the fork, so TA forks have closed dropouts.
On Surly's website at least, one easy way to tell if the fork is for thru axles is that they picture it with a thru axle screwed in, e.g. this pic of the Trucker fork: (note, link goes to the US website)

It's also worth mentioning that the Straggler fork you linked to was for International Standard (IS, usually called post mount) disc brakes. Current drop bar bikes use the flat mount standard, although some older ones (around 2014-2016, I think) may have been for post mount brakes. Just make sure the brake system is correct for the rest of your components.
