At your age you have the time to wait out some discomfort (say RSV in EWR). CAL and NWA are both career destinations...let's assume that the NWA pilots will fix some of their issues in the long-term.
Where would you rather spend your career? CAL or NWA? Go there...
If the answer is FDX, better stay at CPS and get the PIC. If cargo doesn't work out, you can still flow through to NWA.
