Both commercial aircraft and biz jets are type-rated aircraft, meaning that sooner or later, you'll need to log some experience on them. However, doing an apprenticeship in GA will still get you your Cert IV and trade certificate.
As a qualified avionics AME, I can tell you that you'd be a hell of a lot better off going the mechanical stream, as the Part 66 licensing system makes it relatively simple to become a B1/B2 LAME when you start as a B1, whereas no one seems to have considered whether B2 LAMEs might want to get their B1 endorsement...
So yes, there's some (more) food for thought.
