As a variation to my previous question about the domestication of microbes
So my question is : which animals lend themselves to domestication?

There are several criteria which decide how useful animals are as domesticated lifestock. When you pick your lifestock, you first need to consider which animals are actually useful to you. A useful animal is one which provides you with one of these:
Preferably you want an animal which ticks many of these boxes. One of the best multi-purpose domestic animals is the camel. You can shear it, you can ride it, you can milk it and you can eat it. But specialized animals can also be worth it. Pigs, for example, have no use for us except their meat, but are still worth it because no other domestic animal gains weight so effectively.
But then you also need to consider if you actually can domesticate them. In order to be domesticable, an animal must fulfill certain criteria:
Domestication generally relies on taking an animal which already displays useful social characteristics and slightly modifying those characteristics to make the animal useful for humans. Dogs, horses, and sheep are all naturally group-dwelling social animals who take care of their young and form social bonds with one another.
No animals even close to the size of your humanoids have that sort of social behavior. Most of them are parasitic arthropods.
It's also important to consider that domestication isn't so much an intentional process as it is humans and animals slowly coming to rely on another due to frequent interaction. So most of the domesticated animals on earth were domesticated because they did not avoid humans- usually because they ate food scraps that humans left, and they were useful in some way, so humans let them. For example, cuy, or guinea pigs, were domesticated in Peru because they fed on food scraps near people's houses, and humans let them because they're good for food in times of food stress, and they became important ritualistically in traditional medicine.
