I don’t know whether this has been brought to attention here before, but in 2015, TI produced extensive series of brief video-introductions on op-amp design issues and use, which I hadn’t stumbled across before. So, maybe some others haven’t either. Under the sub-topic titled, “Low distortion design”, there are four videos. Most of which are less than 15 minutes in length. I recommend at least viewing the fourth video there titled, “External Sources”. It goes over sources external to the op-amp which can provoke distortion, such as supply regulator output impedance, input and feedback capacitors and SMD resistors.
