Well, what I'm talking about is really an industrial process. There
are probably gas compressors and funky chemicals involved, normally.
The dipping in water method might help somewhat, but it's still rather
a far cry from what's done with raw shrimp, say.

Sounds like you made a 17th century strawberry fool. ;-)

Sometimes there's no really practical way to freeze things and not
have them undergo some structural change. Strawberries have a lot of
water in them, and it expands as it freezes, which tends to mess up
cell walls. There are chemicals you can use to limit the damage, and
it helps to freeze things really quickly, also to limit the damage,
but it's hard to completely prevent it in some foods.
I'm not sure to what extent a water dip before freezing would have
improved the finished product, assuming no chemical additives to the
water. As I say, for some things, freezing just isn't going to be good
for it. I'd almost want to suggest a light blanching in simple syrup
before freezing might be best (and still not perfect).
