Is there any type of software or plugin that you can choose for your project that will give you the Fight Club Look or the Se7en Look and many other looks that I can just choose, play with the settings and get one that I like?
Yes, there are many. Red Giant's Magic Bullet Looks comes to mind, but there are several others depending upon which version of Final Cut you are using. There are also many online tutorials which cover using the built-in effects to achieve the same thing with a little more work. Google is your friend.
