A player just getting started should play a dwarf, elf, halfling or human. It doesn't seem sensible to me to try to make things simpler but at the same time including every possible option.
The options only matter if we start getting into mechanical options. And in those cases, Elves, Dwarves and Halflings are all more complicated than Dragonborn, Half-Orcs and Tieflings.
New players should play the race they find most engaging that is available within the campaign. The race that they find most interesting and engaging is the race that is going to keep them interested in their character and engaged in the game, and is more likely to get them to role-play the elements of that race they find most interesting.
Suggesting people play the core 4 to "keep it simple" when more likely than not they aren't even looking at the stats yet, is really saying "play the core 4 because they're plain." and playing a race because it is the most whitebread has never been a way to keep people interested in any game.
@OP: I've never heard of 5E being difficult to get into for new players. When I ran the game, everyone picked it up pretty quick.
