I wouldn't include dividers such as "Featuring", or "And" or "With". They come up fairly often and add nothing but confusion to the Cast listing.

I guess that's a matter of perspective.  I like them, and have entered them, as they do have meaning.  Often times a well known actor will receive "last billing" when they play a smaller role and they are usually preceded by an "and" or "with".

As to the original question, I don't believe the rules indicate a 'correct way' for these types of headers other than they are allowed.  Beyond that, it seems like a trivial issue so I'll just leave it at that and return you to your regularly scheduled program.

The issue I see with Featuring et al is that they tend to be sub-sections in the opening credits but not in the closing credits even though the same actor is listed in both. In contrast people under Soldiers, etc. generally don't even make the opening credits, so it's less likely for cast member to be in a sub-section at the start of the movie/show but not at the end. That said, it's a relatively minor issue so if someone put them in, I wouldn't get into an edit war over it.
