Instruct. My story, instructed at UND for almost 2 years and then got on instructing for at another place for more money. Got more than the mins for Skywest and I'm here now on the RJ. To say the interview with be harder for a CFI vs 121, not too sure about that. Which aircraft would you rather have to draw out systems, ERJ/CRJ or Seminole/Baron. I'm not saying anything bad about going to a low time place (I got on with Big Sky but turned it down) but the important part is that your overall knowledge and experience with go way up once you move on from UND instructing. However, do apply to UND if you get the chance to instruct there. My two cents.
