My anecdata with waxing - I've not noticed any less performance post-rain (currently using up a bag of SILCA Secret Chain Blend), but then again I do have full length guards/flaps. What I have noticed is far greater lifespan of cassettes, chainrings and jockey wheels. There just isn't the grinding paste you get with wet lubes - 30 seconds with a hairdryer and my chainring just looks new!
Plain paraffin available here plus others, depending on how tarty you want to get with PTFE etc https://hagenautomation.com/products/pro-chain-wax
