These are so many things.
She would like to keep her past life memories. Perfect past life memories seems unnecessary given that she does not have perfect memory of her current life (or is it past, already??) to begin with.
Lifelong luck would be extremely useful, it's incredible that that's even an option. Maybe it's expensive? (She assumes she did not purchase any lifelong luck the last time she made these decisions, given that she was randomly hit by a car at age 22).
Quick learner would also be useful. High class ranking is unnecessary, but might be helpful to her in working to avert various cataclysms. So, that depends on the cost.
She'll take a disadvantage. Born with enemies is fine, imperial enemy seems also fine - can she ask for more details about this Galactic Empire? Also, what sort of unpopular backgrounds are on the table here, is she able to know or select details about her range of options there?
