Selective Grease/Web are useful in the early game. Shout is also great. Then we move into Evocation crowd control like Icy Prison and Selective Sirocco. With Sirocco, Selective Caustic Eruptions, and Bolstered Chain Lightning, the damage from Barrage will be tolerable. And you still have Illusion control spells to make your enemy lives (more) miserable.
Selective Metamagic is mostly used for things that are a pain to work around, like Sirocco and Caustic Eruption. Bolster is for damage spells to give them more oomph.
