I think they integrate fine as long as there aren't problems in the placement, which can be hard to see sometimes since the placement views can't be seen at the same time if they are coming from two different provinces.

If my main army is strong enough though then yeah, I might put them in an area I know won't cause a conflict, and give them "hold and attack" or even Guard Commander as you suggest. Depends on their types, too.
