There's no such thing as a beginner's cup I'm afraid. Although if you want my personnal opinion, that would not be the Mooncup for several reasons (low capacity, thick firm rim). Everyone is different, and what matters here are the facts about YOU. Cups fit inside the vagina, so the first thing to consider is your anatomy : you want the cup to not be too long, and also not be so tiny vs. your anatomy that you can't reach it to remove it. So what I mean by size is mostly length (*preferably measured while on your period to be most accurate, because that can vary), vaginas don't really have a given width, they're usually closed and stretch to accomodate things. Start your research here : http://sizecharts.livejournal.com/

Consider actuall size and capacity, NOT what they are called. As you can see, there's a world difference between a small Sckoon and a small Diva, which is closer to a cross between a large and an XL Meluna. If you have a heavy flow, try to avoid lowest capacity cups if you can (Mini Meluna, Mooncup/femmecup, small Ladycup). You might find a large sized cup will work better for your size and flow. That's perfectly fine, cups are folded on the way in, and possibly onthe way out as well.

Once you've considered in which size/capacity ball park you fall, narrow it down by stiffness : http://menstrualcupinfo.wordpress.com/cup-stiffness-comparison-chart/ I personnally believe softer cups are easier to fold tightly for insertion and removal, less likely to put pressure on your nether regions, and not much difficult to use at all.

Good luck and welcome ! :)
