At nearly 60Kmi, I'd probably do transfer case fluid, rear differential fluid, and the transaxle fluid and filter. Couldn't hurt to do the coolant as well.
In the owners manual for my 2016.5 CX-5, the recommendation for transfer case and rear differential fluid change is spoken of, specifically with regard to "tougher" conditions. If towing a trailer, using a car-top carrier, driving in dusty/sandy/wet conditions, extended periods idling, extended periods low-speed operation, repeated short trips of <10mi, in which case it's recommended to swap new fluid in both of these at 30K miles. If neither's been done yet, it's time for both.
The transaxle fluid+filter swap isn't specified by Mazda, of course. But many recommendations from others, here on the forum, suggest changing in the 50-60Kmi range makes sense. If at nearly 60Kmi, I'd do the transaxle fluid+filter change as well.
Some swap all three as early as the "tougher conditions" Mazda suggestion of 30Kmi, and at every 60Kmi doing the transaxle's filter (requiring dropping the pan). In another 25Kmi (just past 150Kmi), I'm due for all three again, including the transaxle filter.
With the coolant, after the first swap it's recommended to change every 60Kmi or 5yrs. So, doing your first coolant change at that interval couldn't hurt. Probably a bit early, if going by Mazda's guide, but I also changed out mine "early." If nothing else, it helps give an indication as to the coolant system's effectiveness relating to corrosion; if the fluid looks cruddy or has clear evidence of contaminants in suspension, the coolant might not be doing it's job, and I'd want to know that prior to 120Kmi of usage. But, that's me.
