Do you like the hiring manager? Do you know if you'll be working on an interesting (if unlikely to be cutting edge) stack? Do you find the application domain interesting? (Meaning, if it's creating HR services, for example, are you stimulated by that?) You'll learn stuff no matter what you do at your stage of career. Working at a bank will teach you how to ship reliable software in a process-heavy, risk averse environment while learning to develop your professional persona in a buttoned-down, hierarchical environment. That's not a bad thing, but it's a radically different set of soft skills than you'd get working at a startup. The fact that you're questioning the ethics of taking a job with the intention to leave or renege on an offer says good things about your personal integrity. Keep in mind that acting contrary to your own values is a discomfiting and stressful experience.
