It does not, however cover the zero-tick cactus farms that became possible in 1.13 [ eg https://www.youtube.com/watch?v=NkV9iXii9_4 ] If your definition of best is most items per volume or most items per hour, these are currently unbeatable.
Since I don't have a use for very large quantities of cactus, I use a mix small manual farms positioned where they are convenient to harvest eg. near a cage grinder (using slimeblocks as the breaking block works nicely) and small 12-16 cactus farms hung over the upper water floors of iron farms (or similar water collection systems).
