Good choice! The Dual Cursed Oracle is an excellent archetype and its revelations are well worth taking. You're basically a walking hero point generator for missed rolls, and that's just fantastic.
For spells, unfortunately the level 1 Cleric and Oracle list was a little boring until some recent additions. That said...
Command and Forbid Action are very helpful if you use them right.
Bless and Bane are both decent low level options.
Summon Minor Monster is a surprisingly powerful spell if you choose the right animals (like weasels!).
Depending on the campaign, Remove Sickness may prove incredibly helpful, and your party does have a few low-fortitude characters.
Obscuring Mist never goes out of style.
The new Ironbloom Sprouts spell is basically Goodberry with a twist, and Goodberry is a very underrated spell.
Bleeding Strike is good against anything with a pulse.
Murderous Crow is interesting in the hands of a clever player.
And Murderous Command can really mess with an enemy party on a failed will save.
Hope these recommendations help!
