“Neocon” means a lot of things. On foreign policy it has come to mean pro-Israel, anti-Cremlin, anti-terrorist, pro-freedom (in the sense of aiding opponents of our enemies) and if needed unilateral US action.
This is also where Palin stands. One could also call it common sense, strong US foreign and defense policy.
Domestically the “Neocons” are indeed Democrat-lite RINOs ala Giuliani, Romney, Frum etc.
This of course is were she stands opposed to it.
Bill Kristol is generally considered to be a neocon, does not take the positions you mention, and was one of Palin’s earliest backers.
The GOP types who oppose her tend to be the ones called ‘crunchy cons’ for some reason.
