Conclusion
You will have better access to Cathay Pacific awards through its own Asia Miles program than via partners, although some partner programs price them more favorably (look at Qatar).
If you have been contemplating converting from Citi to Cathay, now would be the right time.
Just make sure that you have a plan to use them efficiently.
