Shenron's got the right of it.
Class and Race options being limited don't "Streamline" the game. They just limit the number of options at level 1.
To streamline the game you need three main things:
1) Less dice rolling.
2) Shorter turns.
3) Simple concepts.
This is more "How would you reduce the bloat of D&D 5e" but for some reason doesn't -touch- on the progression bloat that is spells and magic items which increase the bloat of the game dramatically as you gain access to ever more fiddly versions of everything.
