There are many writing genres including, but not limited to, fiction, non-fiction, children’s, self-help, and spiritual writing. Most publishing companies will publish any of these with a few exceptions. Finding the right publishing company will take some research on your part. A trip to a bookstore or surfing Amazon can help.
If your niche is children’s, go to the children’s section and check out the publishers. You will find that a few publishers will start to stand out. Make a list and dig further with a website search. A lot of published authors will write reviews of the publishers they have used. This is especially important if you’re going with a vanity publishing house or self-publishing.
Knowing your exact genre can help. There are so many sub-genres from the five listed above that it pays to know what category your writing fits before searching for a publisher. There are a few websites that provide a complete list of genres. One can be found here.

Children's books follow along with the same genres as fiction (excluding Picture books). Poetry, Folklore, Action/ Adventure, Science Fiction, and mystery. The children's author needs to know their target age group and write appropriately for that group.
Self-Help books come in a myriad of topics. When writing self-help books, the writer should know that the topic will help some. That's the ethical delimma. Self-Help books are the largest selling genre.
All spiritual writing should be inspiational. Whether it is about a particular religion, a fictional tale, words of encouragement, history,or a book on affirmations.
