all those procedures you describe (Kai Tak, JFK etc) are very, very different
Absolutely ....and there is also an official "side-step" manv. promulgated, e.g. last time I landed at LAX ( a long time ago, so may not still be relevant) ATC cleared me for the ILS to 25L with a "side step" to land on 25R ( I think they actually called it 24R to help avoid confusion ? ) and being a 'foreign' airline the controller came back and said he wanted to ensure that I understood, that I was to complete an ILS to 25L, but once past the outer marker, at my discretion as to when I made the switch, I was to complete the side step manv. and actually land on the parallel runway - having subsequently been given landing clearance on the runway they wanted us to land on of course.
The reason, I think, was to allow more aircraft to be accepted for the approach, had they had to provide the appropriate separation behind aircraft on each runway, ti would have slowed the total traffic movements down, by 'mixing and matching' they got a greater utilisation of their Real Estate - I think ?
Was fun !!
