Be suited to is actually a very good phrase. I don't see why you would not want to use it... However, if you wanted to use a different word you could say appropriate, applicable, apt, convenient, fitting, befitting, and many more - consult your local thesaurus.
We don't really say suit something to something but we can say something is suited to/for something. A fish is well suited for swimming; mice are well suited for being test subjects.
Hope this helps,
