When people speak of "diphthongization of high long vowels" I always had thought of them as [ɪj] and [ʊw], i.e. only lightly diphthongized. (I only diphthongize mine when I have /uː/ after a coronal/palatal and before a dorsal, as [yu].)
There's register-related alternation; careful [ɪi̯ ʊʉ̯] ranging to casual [əi̯ əy̯]. In unstressed syllables (happY) you might find [ɪi̯] or perhaps even [i], but always [əj] before a vowel ([ˌhæpʰəjɜzˈɫʷæɻɪi̯]). "to" and "gonna" both end in [ɜ] in normal unstressed position, but [əw] (or ?[əɻʷ]) before a vowel; likewise "the" is [ðɜ], [ðəj] (but never *[ðɜɻʷ]).
My FLEECE and GOOSE vowels are pretty centralized, but not all the way to schwa. FLEECE has spread lips and GOOSE has rounded lips. And happY is consistently [ɪj] (or maybe [ij]?), even before vowels.
FOOT [ʊ] vs. NORTH/THOUGHT/FORCE/CURE [ʊː]
You really have [ʊː] for NORTH/THOUGHT/FORCE? For me,
full [fʊl] and
fool [fʊːl] are a minimal pair for vowel length, in contrast to
fall [foːl]. Do you merge
fool and
fall? (Though now that I think of it, some people have the LOT vowel in
fall, so maybe that's how they're distinguished.)
