So the situation as far as I know is that neither fan runs at low speed and one fan is intermittent at high speed. It definitely didn't trigger a couple of weeks ago when the other fan was running at high speed. But today both fans definitely were running at high speed as normal. Would this be the resistor pack?

Also, do the replacement motors come with resistor packs?

Yes. The parts geek fan has the resistor and the whole assembly is about $160.the resistor alone is about $110, so it makes sense to buy the fan assembly and replace everything to be on the safe side.
