Limited Wish is where it is at, as they say.
I managed to grab an item through my GM to yoink Spell Domain, giving me Limited Wish in a domain slot.
And I take it EVERY DAY. And when I need it, I use it. Usually to emulate a Wizard spell I need. My character got dropped a mile up with no flight spells ... and I whipped out an Overland Flight from the Limited Wish slot. Actually it was an Extended Overland Flight (which might be a little tch under the rules, we never looked it up, but it works for us).
We actually had one guy with a calculator computing velocity and distance traveled before I could get the spell off and pull out of the dive ... that's a fun fight!
If you're limited to the two spells for right now, and want generality, I'd go with the Greater Shadow Conjuration.
You're basically metamagic'ing spells at that level, then. You're paying one slot more to get a whole passel of spells without needing to prep them, from lower levels. That's a nice generalist touch, letting you be prepared for a bunch of eventualities with fewer memorized spells.
