I'd say resistors totally fine if they can handle power you need. As of smd caps, depends where and what they do, DC bias being, probably, the biggest problem. I wouldn't use smd caps smaller than 0805, but bigger packages, while having better specs, are more fragile and can cause a short.
Anyway, I wouldn't care much about distortion, etc. Unless you have "golden ears", I doubt it's audible to have 0.1% or 0.01% distortion, let alone making a difference in experience. I know the pressure in audio community for "special" cables, resistors, capacitors, opamps, etc. Probably that's why you are here asking this question. But look critically at the plots you showed. Are you really care about resistor noise of <-110db?
My advice: get an audio analyzer if you really care and see yourself how different components affect distortion and noise. Otherwise just use normal components and save yourself a lot of time and trouble.
