Captain,
With all due respect, I think you are planning a little too much at this stage. Your well thought out posts tell me that you will likely have no trouble succeeding in your career. To plan everything out to the extent you are however will likely be a waste of time. Since I started out in aviation, I have been furloughed four times and gone through 2 bankruptcies. The airline that I dreamed of flying for before starting out is long gone. Things change in this business and they change fast. In the course of building your experience you will meet a great deal of very wise people along the way. As you talk to more people and build up your own experience level you may very well change your mind about where you want to be. Some of the happiest pilots I know decided to forget about the airlines and stay in the corporate world. At the end of the day it's all up to you.
To answer your question about Cathay Pacific, with the 1700hrs that you say you'll have when you finish your program, you will be nowhere near the experience level required to join as a F/O. You will even be far from the level required to join on the Passenger fleet as an S/O. Currently many of the joining S/Os have 1000s of hours of jet experience. Don't pay too much attention to the minimum requirements posted on the CX website as they are far lower than the actual experience level sought.
Good luck with your career.
