Since you don't appear to have sat for any previous coding certification exams, I'd recommend the CCA.
I know many folks who tried to take the CCS right off the bat and did not pass. A coding credential, even if a junior one, is better than none for marketability. Also, by demonstrating a level of devotion to your career, you may gain an employer who will pay for and encourage your attainment of the CCS later on.
Personally, with 6 years of VAST coding experience in almost every major setting and several years of formal education, the CCS was a challenge for me.
Good luck to you.
