I'm trying to figure out what would be the next best spells and/or feats to get, since I've gotten pretty much all the spells I really wanted. Is there something I'm missing that's awesome or would just make life that much easier? Or even something that's pretty neat, even if it's sort of niche?

For background, character is PvE only, preferably cursed/undead and doesn't do sorcery.

I know I'm a bit late responding here, but the Cautious Casting feat was really helpful for me. It helps when you are trying to snap cast and mistype the mana on the prep so that nerve damage doesn't add up. Injured Casting is also helpful when you're beat up, but still need to be able to cast a spell like SICK or PS while you retreat of flee from a sticky situation.

The Mastery feats I usually find you can get a bigger boost by switching alignment. Aspects of the All God lets you do that on the fly, which I think you said you have now anyways.

Deep Attunement to me feels like a waste because Persistence of Mana never leaves me needing more mana.

The Magic Theorist and Improved Memory feats are great for saving spell slots. You can forget LW and GAF and get 3 spell slots back, use 2 slots on those 2 feats, and then INVOKE any 2 scrolls (such as GAF and LW).

Pick up some paladin spells such as Courage or Righteous Wrath or Rutilor's Edge to play around with too.
