Okay just looking through magic weapons, the different specific abilities, etc. there seems to only be 4 alignment enchantments Axiomatic, Anarchic, Holy, and Unholy.
All of them align a weapon against a specific type of DR, but they also add additional damage dice and all are +2 enchantments.
So the answer to the question I'm looking for is what if I just want to align a weapon. Say I want to make a +1 short sword that is good aligned, not holy, just good aligned for the purpose of getting through damage reduction.
Are there actual RAW for this or would it simply be house ruled as a +1 enchantment?

No RAW that I know of. Align Weapon is a level 2 cleric spell, but it cannot be made permanent via Permanency. The GM may allow other spells to be made permanent.
While it is not stated explicitly it might be possible that intelligent weapons alignement could penetrated corresponding DR.
