The third group there is already mimicked by most races we have. Rakasta, catfolk and tabaxi can be done with elves. Lupins can be done with gnolls. Bearfolk (or Pandaren, for the WoW-inclined) can be done with goliaths or even minotaurs (refluff gore with bear claws). Ratfolk can be done with halflings.
Yeah, but that's a little reductionist. By that logic, we only ever need Five different options. Human-Dwarf-Elf-Halfling-Halforc-DONE.
There's plenty of room for options that aren't reskinned other races, though I do think it's important to make them very distinct, if it risks hitting close to another race (like halflings and gnomes are pretty distinct in my mind, with one being the stout, doughty, suburban crusader of childlike innocence, and the other being the sneaky, brilliant, badger-using illusionist of diabolical trickery).
