Hi B&G, welcome to the forum!
You will find that your Villages Sales rep will be attentive to your questions and honest with answers. You're gonna love your visit and you can set your own pace.
In answer to your stucco question, I would suspect that stucco is a wee bit more soundproof, as the walls are thicker. You lose a few inches in the interior floor plan because of that, but it's minor.
Stucco requires a bit more maintenance, as it must be painted every so often, and could require crack mending occasionally. Siding is vinyl, so it does not get painted.
Both stucco and siding require washing once or twice a year. (Don't know if one is harder to clean than another.... most of us use an outside service for that. Termite control is used on both kinds of homes.)
Stucco is a little higher in price.... for equal sized CYV's for example, expect it to be maybe 10 grand more. And, of course stucco looks elegant.
I LOVED stucco and hoped we would end up with it. It felt Floridian to me.
The home we chose had all the things on our wish list EXCEPT for stucco.
I am happy with our selection and now that we're in here, our home reminds me of a Michegan beach cottage.... and both FMF DOC and I love it just the way it is.... so you can't go wrong either way.
Happy hunting!
