Enthusiastic "Re-Beginner"
Platys, Swordtails, Mollies, Guppies and Endlers are all among the livebearers and as such you have to think about the possibility of tons of baby fry. Most of these will breed non-stop. This can create a couple of problems for beginners: first, it can unexpectedly raise your tank stocking load, having cycling implications if your filter is immature; second, it can get you into a cycle of always trying to find people who will take fish from you so you don't have to buy new tanks. There's nothing wrong with this - I only point it out so you can go in with your eyes open. For some people these things are what its all about and what they want!
Of these, platies and swords and perhaps endlers present the fewest problems. Mollies have the trickiest water chemistry needs and guppies can be rather non-hardy sometimes these days. I can't comment much on endlers, which are great for tiny tanks. Mollies are definately "do-able" by beginners but I usually think beginners would at least be better off if they did more research on them before getting them.
There are probably tons of fish that make great "first community fish after fishless cycling." A few that come immediately to mind are Zebra Danios, Rasbora Heteromorpha (Harlequins), 2 or 3 male platies, many of the larger corys, lots of types of shoaling tetras. Plenty of barbs are hardy but they of course usually work better in tanks of bigger fish.. cherry barbs might be an exception, not sure. Researching the various common tetras is a good direction for beginners to go in I feel. There's lots of choice with many different looks and productive and clear cut things to learn from the research.. certain ones are very nippy, so you'll not want them but others may be great. Nearly all of the tetras will have minimum shoal numbers to find out about.
Angels, cichlids and various other big fish more often fall into the "centerpiece" category for many beginners who don't happen to have huge tanks. Often people will wait some months on these just because they are expensive and they want the tank to be even more stable. Beginners often don't realize how much more stable there tank will be (ie. water will be even nicer for the fish) at 6 months and at 1 year, but that's usually a reality.

and from this experience i can say they are extremly hardy. they make excellent community fish too, and if u get all males or all females u won't have to worry about excessive breeding. the same applies for swordtails from what i've seen. both are very active fish, and great to keep u entertained. both come in a wide variety of colors and patterns and u should be able to find something that will complinant any future additions to ur tank.
