Wetsuits:
The basic issue with wetsuits is that in addition to making open water swims safer by providing the wearer with added warmth
and flotation they also provide a speed advantage. The speed advantage comes from the added flotation that puts a swimmer's
body in a higher and more "correct" position. This is the position that a good swimmer swims with anyway by using proper technique. Wetsuits are allowed depending on the water temperature.
Therefore, wetsuits speed-up a poor swimmer with poor body position much more than they speed-up a swimmer that already uses
good body position.
As the sport evolved the largest emerging series used these distances. The origin is not exactly clear but a 1500m swim is the standard "long" swim race, the 40k timetrial is a cycling standard, and 10k is the most popular road racing venue. The international triathlon governing bodies needed a distance to promote for the Olympics and picked the "most popular" format.
