For Sorcerers, you always have Human special favored class ability to massively swell your spell list, so the freebie spells are best focused on those sorcs can't normally get.
Mostly you'd be looking at the uniques, especially the bloodline arcana if you plan on multiclassing out.
Boreal: Other than Enlarge Person and Wall of Ice, its spells are not exactly that useful for a GOD, but the bloodline arcana is easy to apply to your spells for free DC increases and Snow Shroud turns Fogs into a one sided drawback, as you can see through the mists. Blizzard kicks in a bit late, but it does save on spell slot pressure for screwing up battlefields. Feats are rather mediocre though.
Dreamspun: A fairly nice list of useful spells, though the bloodline arcana is rather situational. The initiative bonus is not to be sneezed at, though the other specials are a bit random, they are reasonably useful. The feats are pretty sad here.
Fey: Some nifty druid spells to your list, Woodland Stride is rather situational, but useful for positioning in outdoor campaigns. The bonus to compulsion DCs is downright nasty as a backup plan. Theres a couple of useful feats here.
