Become a CFI, you will learn some very valuable things about flying.
Flying is not about getting a job and building flight time. It is about being a good, confident, and most importantly, a SAFE pilot. Earning a CFI will contribute to all 3 more than anything else. It is well worth the investment.
Also, why would you want to work for a stepping-stone to another-stepping stone? That is a waste of time, effort, and life. Build up some real time as a CFI, become a real pilot, then find the best regional you can find and work there. You will be happy you did.
