Yeah you'll definitely have more options after naturalization, but it won't be so 'direct' if you know what I mean. i.e. in my scenario, if I had my citizenship now I would just go straight into OCS without a problem, but we have to jump through hoops on everything in life as you know
Basically even after bcs, you're obligated to the contract you signed to enlist, so you have to ride it out or look into programs like the ROTC or SMP(Simultaneous Membership Program), might be something maybe you want to google, as far as I know that'd be the 'easiest' way to transition in after enlisting/naturalizing.
