My personal choice would be none of the above in the poll. I shall explain.
IMO, angles are going to get big, and they are very territorial, and adults can get nasty. They are a cichlid after all. Unless you plan on starting with maybe 8 small ones, with the goal of ending up with a single mated pair, I'd avoid them.
African cichlids are very colorful fish, and do have a lot of personality. Like angles, they get big, territorial and nasty. They also like to dig. This makes the tough on any plants you might want. If you want Africans, use a lot of rocks and really tough plants.
Platties and swords would be a good choice, if you could find some decent stock. IMO most of the livebearers seen to day are of very low quality, and not something I'd care to own. However, if you can find good ones, this would be possible.
I do like the idea of rainbows. This is a group of fish that is large enough so you raphael cat will not bother them, and are highly colorful.
My own personal choice would be to get rid of the raphael cat, and stock a planted tank with tetras.
All that being said, it's your tank, and you got to choose what works best for you.
