You'll either meet the required standard, or you won't. If you want better training than you'll get at a commercial flight school - join your nation's air force. The big name schools are often very directed - but that can actively work against you seeking a more interesting flying job than an airline job.
The two standard routes to an airline flight deck are "zero to hero", or via being an instructor. A recent American study showed that people who have been instructors tend to do better in line training.
But if you are going to be an instructor - like BEagle said, take that job seriously, and be the best instructor you can be.
