... with my B737 hat on, I don't remember any guidance for adjustment of approach speeds due to precipitation, just the usual allowance for gusts up to a maximum figure.
Nor do I remember any talk during training of any significant adverse effects of rain on jet airliner wings?
Microbursts yes, but the direct effect of any rain associated with them, no.
Maybe 'scale' and speed dictate the likelihood of adverse affects due to rain rather than laminar flow aerofoil sections as such? - Big fast jets against slow small gliders?
