You have stated all panels are in the same location. Thus, load location is of no importance.
First I would separate the loads as follows:
1. Put all the refrigeration equipment in one category. This does not mean on the same panel.
From your list 2 wine fridges, 3 -48 inch fridges, 2-36 inch fridges, 2 wine fridges, and wine cellar cooler. These are what I define as a "continuous cycling load". The on time might be 50% with the total cycle period about 1 hr. But they won't be in synchronization or have the same cycle time. These as a group probably have an average load about equal to the sum of the average load of each unit.
2. All air-conditioners in another category. These are also a "continuous cycling load" but may operate only half of the year. However, the half year use information may be of no value.
3. The 4 washing machines and electric dryers, double wall over, sauna, 1 ice-maker, 3 dishwashers, disposal, dumbwaiter, (what about cooking equipment) are what I define as "non-continuous cycling loads". These cycle when on, but are on for only limited times.
4. The space heater is probably a "continuous cycling load" part of the year. What other heating equipment is there?
5. You did not mention lighting. If possible the lighting should be on one panel that has the least common impedance with other panels, and if its panel has other loads, then these should have the least inrush current and large cycling current.
From the way the loads operate you need to distribute them to produce the least heating in the panels, and least interference with lighting.
Conceptually separating the loads in this manner may help with your distribution. Obvious you need to consider the NEC criteria, but you want to minimize light flickering. You pick the category for the pump. There are a lot of motors cycling at different times that will cause inrush voltage dips.
