halacha - Borer and Grinding on Yom Tov - and other Melachoth that are Ochel Nefesh

Which Melachoth are prohibited on Shabbath but are permissible to perform on Yom Tov because of the exception of Ochel Nefesh? Famously, cooking and carrying in the public domain are allowed, yet igniting a flame from scratch is not. Furthermore, some other actions that would seem to be Ochel Nefesh are also prohibited. What else is allowed? Are Sorting and Grinding on the list?

I am also fairly certain that there's a difference between Ashkenazi practice and Sepharadi practice in some instances. Please provide sources for each.

(Please don't list smoking as permitted as cooking but should be prohibited because of danger, or other such exceptions to the exceptions. I'm looking for general categories of Melachah, not unique subcategories or specific types of actions. If a category is permitted only under certain circumstances, such as squeezing a lemon on a solid but not into a liquid, which is permissible on Shabbath anyway, that should be noted.)
