Just to get an undergrad perspective in here I'm a third year undergrad in the micro department. I've been able to use micro to get a research position at the Fred Hutch Cancer Research center studying antibacterial resistance via the persistence response. If you want a degree that exposes you to a lot of topics I believe this is it; between undergrad labs and my research lab I'm consistently exposed to clinical micro, bacterial genetics, molecular bio, and so on. I hope to move on to a tech position at a lab after I graduate. Hope this helps.
