Difficult to answer when there's already so much you can pull out of your ass and so much more you appear to have the potential for but haven't figured out how to do yet. Time travel sure would be convenient as hell, though.
Teleportation, like basically every trans girl out there. I mean come on, getting from point A to point B takes enough time even in a big sprawling space empire!
Being able to speak every language, for whatever value of 'speak'. The translation systems work well enough, as do the numerous interspecies creoles for those that communicate in broadly similar ways to us althoinui (you humans are honestly probably unique in having compatible speech apparatus with our languages outright and vice versa); it'd just be wonderful to be able to express myself more directly, no?
Ah, but what do you give to a woman who already has everything? <3 Well, mostly everything. Actual godhood is a little outside the scope of 'superpower', though.
I don't have much I'd actually actively wish for - but levitation would be fun for the necessary dramatic entrance from time to time <3
The ability to jump between planes, at will. While I shan't go into detail at this time, suffice to say I have my reasons.
... does being able to squeeze through doorways count as a superpower?
No superpower afforded to my physical form could possibly measure up against the infinite potential offered by a mind beyond the comprehension of ordinary sapience and a form blessed with endless modularity.
... that said being able to make my own, physical pocket universes would make for a nice shortcut to things.
