It is a syntactic difference, as well as a difference in meaning, PP (but the difference is slight and occasional, and not as you have suggested). Here is how they construct:
Such a thing = that kind of thing (such + a/an + noun) Such things = those kinds of things (such + noun) Such stuff (such + noun; the uncountable equivalent of such things) Such a big thing = of that size (such + a/an + adj + noun) Such big things (such + adj + noun)
So many things = such a (great) number of things (so + adverb) So much stuff (so + adv; the uncountable equivalent of so many things) So beautiful = of that amount of beauty (so + adj; no noun) So beautiful a day = a day of that amount of beauty (so + adj + a/an + noun)
Of your sentences, only the second is constructed correctly.
