The main question is whether the supplies meet the SELV criteria for
keeping the output voltage limited under the internal fault condition
if they claim compliance with UL 508 and EN 60950-1 but do not
specifically mention anything about meeting SELV.
The supplies must meet the insulation requirements to claim any sort of
compliance at all. The voltage requirements under single-fault
conditions would be extra; probably they would be met but it's not
certain.
Or to re-phrase the other question, is there another standard that
also specifically meets the requirements for SELV?
You mean another standard for complete power supplies?
You could look at standards in the IEC/EN 61204 series. See:

on the public part of the IEC web site.
