This may or may not be relevant to your question and to your needs, but for decades I've been using 559 X1" or 650C ("See") X 23 mm tubes in 32 mm tires and even, at need, in tires up to 60 mm wide, tho' the last only for brief periods in the absence of fatter tubes. But I plan to use the 26X1 tubes in 42 mm Nachez Pass tires once I get around to buying the latter.
Me, personally, I'd choose the 40 mm tubes for 60 mm tires over fatter ones, for the weight saving. (And note that I have been accustomed to patching well over 150 flats per year where I live, before modern sealants came around).
