Most any fin will move you around as a beginner. To a degree, you should really buy fins that you will want to use as general purpose (what will you need for 80% of the diving you are intending to do). Once you get the fins that will do what you want, you need to get used to them. You'll do better to get in shape for the fins you want, rather than getting fins for the shape you are in.
Get what ever fins you want because you will never really know what you like until you have some dives under your belt. Besides it is probably going to take quite some time before you can even appreciate or notice the differences in a fin anyways. So after some time and and bunch of dives you will finally know what you expect out of a fins performance and by then you will probably want a new set of fin anyways. Get what ever makes you happy at this moment.
