It could also be symbolic, in which case it's harder to tell what it is.

With work, I reside,
With work - either as it sounds, or with the word "work".
To reside can be either to live with or to exist with. Those are the only meanings I can think of right now.

To help out the royalty,
My bet would be that this is not as easy as the royalty in-game, but rather like you did in your FFVIII riddle, where "royalty" referred to Solomon, a real life ruler/royalty.
To help out is probably what it sounds like.

With their work and their pride.
The word "their" suggests that the royalty spoken of is not just one, so maybe it is in-game royalty after all.
"work and pride", well, I guess it's sort of what it sounds like.

I'm not on the outside,
As my work is within,
Works inside a castle, house or just in a closed group? Hard to tell.

My name is the top,
Of the others aboard.
This seems like word play or some sort of visual guide.

I'll guess Blutzen, mostly just to make a guess. He is the topmost Pluto knight on the list apart from Steiner (Steiner would be too obvious).
The rest of the reasons for that guess are self-explanatory with that reasoning above.

this riddle isn't as twisting as my usual ones. The majority of it is straight forward.
Greatest kingdom is in reference to most powerful in 'some' circumstances, but greatest/largest in capacity.

One of the words in the second verse gives you a clue to what 'career' I'm on about in the riddle. Look carefully for it, but as I said the rest is normal and straight forward.
