I have watched that anime where the MC asked to make her abilities average, but she became average among ALL beings rather than just among humans.
I initially was going to ask that, but I thought of something better: What if you reincarnated with your abilities balanced instead of being reincarnated weak, strong or average?
Depends on how you find the balance. Bacteria, protists, and insects vast outnumber humans and all mammals while having simple to no mind. So if I were to be balanced, I would put limits on what is selected. If I were pure average for all humans, I would have been born in or nearby China, so that is another thing to look at. I would also want to know if I start average, or if I am updated as an average changes.
If my world of reincarnation has magic of any sort, I will first try to maximize my learning capabilities, but if that doesn’t help I would go for balanced.
