I have no clear answer, but I'll give you my 2 cents about the options you stated.
I agree with Seeker (or any other similar trait giving Perception as class skill) being almost mandatory. You might like Underbridge Dweller too: the benefit is essentially the same, but fits better with the campaign since you will move to Magninmar at a certain point (it's the closest big city to Sandpoint, so no spoiler), also allowing you to get a different Social trait, such as Student of Philosophy, Bruising Intellect or Clever Wordplay[UMD].
Favored-son-daughter is cool, but only one is needed per party, so be sure that no-one else wants to pick it (since you don't seem to care much about the fluff, maybe someone else in the party does). Outlander > Exiled is fine if there are no campaign traits you like, otherwise it's the same as Reactionary. Otherwise, if you already know what kind of spells you're going to cast (for example: pit spells) you might like Outlander > Lore Seeker.
Finally, if you plan on crafting magic items, Spark of Creation is essentially a better version of Hedge Magician. Traits in the Magic category compete however with Pragmatical Activator, in case you wanted to use your own UMD ranks. If you want both, you can get Int to UMD via Clever Wordplay.
