[Star Wars] Why was Jango Fett chosen to clone? Wouldn't there be much better soldiers fighting for the Galactic republic army?

The physical attributes and descent, his achievements and the fact that the Republic Army has always been a bit of a joke. Plus they didn't have to kill him afterward, allowing them to use him for other things. The candidate selection was not handled by Sifo Dyas, in fact.

After the project was commissioned, Sifo-Dyas was secretly killed and Darth Tyranus took charge of the project. He was commissioned by his master to do two things in this time period: One, find someone who was an effective genetic template for an army that would eventually be gutting Jedi and playing in their intestines and two: Kill a particular rogue Jedi (who was not fallen).

Tyranus decided to do both at once and put an enormous credit reward on the head of the rogue Jedi. A public bounty, but a number of mercenaries and hunters got special invitations - among them, Fett. He tracked and defeated the Jedi (Not even killing him, just bringing him in alive). One million credits richer, Tyranus offered him the job of being Clone Daddy to the Grand Army of the Republic.

Jango Fett was vetted anyway, but let's stack up his physical attributes: He's a member of the Mandalorians, an ancient warrior culture/race with a reputation for balls-out insanity. He's human, fit, with no major genetic problems. He's just (edit: Embarassed a Jedi), even taking him in alive. Perfect for a thousand thousand thousand clones. Not only that, he's familiar with the training methods of his people, so he can 'consult for the Kaminoans when it comes to training methods.
