I think like in modern pharmacology we will find that there does not exist a prescriptive best for everyone because everyone is genuinely different. We may be able to identify a "best available" for the most common cohorts, but ultimately what works best for an individual will be specific to their unique circumstances.
Eg from physical differences or other issues with their eyes, differences in the way their brains process vision information, to nothing more than cultural habits (it's what they're used to).
These differences show up knowingly or not as preference towards either dark or light mode or something in-between.
So it's reasonable to default to eg light mode since that might be suitable for the largest cohort, but ideally it's best to have the option to switch to dark for those that prefer it.
