Interesting, yeah I always run the sink for 10-20 seconds after using hot water to clear the line. My house isn’t pex (I want to update it at some point) but I also thought it was more the water heater than my pipes that I was combatting but it’s very possible that it’s an old wives tale that I fell for decades ago. For pasta I have a convoluted system of putting a small amount of cold water into the pot and then doing 3-4 rounds of the electric kettle (with occasional additions of cold water when the water in the pot reaches a boil but I still need more water).

If your water system has been doing corrosion control, you’re fairly well (but not 100% protected) against lead exposure from your old copper pipeworks. The big risk is new lead-soldered piping and leaded (largely pre-2014 USA brass plumbing but [1]) fixtures, because even with corrosion control, it takes a while (months to years) to build up that protective layer. What people get wrong with pasta is they think they need a strong boil. While the steam is hotter than the liquid, most pasta is in contact with the water and your energy is going into evaporating more water off. Just use a spoon to stir occasionally and use a pot cover to condense the steam back in.
