Thank you to all for the info
Just trying to understand my (realistic) options
Dude, if you want to kick ass as an aviator, and make it a career, your timing - whatever that may be - is most likely not going to be a roadblock to that. Your squadron COs (along with detailers/placement) have the tools (in most cases) to ensure their due course EP players have all the opportunities they need to be successful and have good paper going into promotion and screen boards. That should always be your goal, regardless of career intentions. Doing otherwise limits your options and opportunities.
Make sure you have that conversation with your Front Office, or a DH you trust if you don't have regular access to your CO/XO, about your timing to ensure they're tracking and planning ahead... they almost certainly already are. Conversely, if you aren't respected in the squadron and people know you plan to get out as soon as you can, then people aren't going to put in any effort to help you.
