Time saver alert. The short answer is "wet", but I'm not very good at short answers.
For the list of balance factors recommended by others, I know that some are wet, but some were not stated as wet or dry, and some probably were, but I've forgotten which. I could probably include some of that info with a little research, but it was never anything I worried about. I've only ever used wet balance values, and just used the recommendations as food for thought. For the individual crankshafts I listed, I included the total bob weight as the significant data point. That was to allow me to calculate the balance factor with whatever combination of parts I might want to use with that crankshaft in the future. The rotating and reciprocating weights listed with each crank are for the components (rods, pistons, etc.) used in the particular engine build I was using the crankshaft with at the time, and the given balance factors are for the crankshaft when using those configurations. All the values of rotating weight include the weight of oil in the crankshaft. The SoCal balancing shops I used back in the day (Ditronic Balancing Company in North Hollywood and Fitz and Miller in Sun Valley) measured the oil capacity of each crankshaft, and used 43 to 50 grams for oil in factory Commando cranks, and 15 to 17 grams for Nourish cranks. When statically re-balancing them myself for different conigurations, I've used the same oil weights for my calculations. A long-winded way to answer your question by saying that they are all wet balance factors.
This list started out 25 or 30years ago as a way for me to keep track of data for my own engine builds, but I later started adding bits of data that I thought others might also find interesting. The next iteration will have some mention of the wet/dry question, if I don't forget all about it by then.
Maybe I can also organize it a little more then.
