For what matters France, I don't think the ruling elites at this moment will go on a real expansion policy.
Remember that Louis XV didn't really push for their interest in 1748 while they could have done so : of course, in the case of a French success in the ASW, it could be different but the mindset for outright expansion doesn't seem to have been really present.
Eventually all depends how the war goes, and which policy Prussia adopted and I think it's likely they'll pursue the "Every man for himself and God for us all" attitude which alienated a lot their allies.
And, really, unless you fix that (maybe with Austria doing better in Silesia, making Frederick II more dependent on France and Bavaria?) I doubt you'd have a decisive conclusion.
Now, admitting a joint Prussian/Bavarian/French victory over Austria/Sardinia/Russia (I don't put Britain, because this is not really a war that could be won over it even if part of the belligerants), what would be stressed by France?
Well, giving the lack of really vital interests it went in war for, you'd probably end with some moderate conditions (Prussia is unreliable, so no post-ASW order, and Britain remains the main problem and Jacobite revolts were to comically inept to be of any use).
Probably some parts of the Netherlands, certainly not the whole of it : maybe sorta return to former boundaries
before Utrecht.
Meaning Ypres, Courtrai, Tournai, Charleroi.
Lorraine is already at this point a French puppet so that's out of the way.
Maybe in the case of a clear victory, Luxembourg and/or small parts of Palatinate.
Anything more in the North is at very best calling for an early SYW equivalent, while alienating every possible ally while painting a target on France and shouting very loudly "ATTACK ME!" to George.
As for Italy, the focus would be on weakening Austria as much as possible, probably by favouring Spain (and maybe, pushing it, taking back some alpine places as Pignerol).
Favouring Bavaria is probably what would happen in HRE proper as well, but less so (less reliability).
Colonial demands is a no-no : there's neither enough money to sustain this, and not enough motivation to take on british colonial empire.
Again, the treaty shouldn't alienate possible allies : Prussia would be a shady ally at best, Austria could be still useful against Britain (France having a real european focus as the key of general conflicts) and generally searches a politic of balance to avoid a WSS-like scenario.
