Are you sure the differences between the versions of the many worlds interpretations aren’t really just normative? I think some would just claim you should treat the quantum measure as the actual measure of amounts of value and disvalue over which you aggregate, so everything gets normalized, and you get back to maximizing expected value as if the MWIs are false and there’s no branching at all.
Or you can say we’re part of a set of parallel universes that don’t split but which is as ‘large’ as the infinite limit of the fastest splitting process.
Maximizing expected choiceworthiness is not my preferred way to deal with normative uncertainty, anyway, though; I prefer moral parliament/proportional resource allocation the most, and then structural normalization like variance voting next. But these preferences are largely due to my distaste for fanaticism.

For dealing with normative uncertainty, if you’re into maximizing-expected choiceworthiness and believe in intertheoretic utility comparisons between the different normative interpretations of MWI, then the expanding version of MWI
should(EDIT) could dominate, although there are infinite “amplifications” of the more standard measure-based interpretation that could compete or dominate instead, as described in Carl’s comment:Amplified theories are discussed further in the Moral Uncertainty book chapter I linked above.
