If you're just looking at the Fender range, then in a nutshell:
Vintage reissues, including American Vintage, most MIJ Strats and the MIM Classic series, have skinny vintage frets and a 7.25" fretboard radius. Neck shapes vary depending on the period (V for '50s, C for '60s, etc).
Almost every other Strat in the current range, including American Standards, Mexican Standards, Highway Ones, MIK Lite Ash etc will have a fairly thin "Modern C" shaped neck with a 9.5" radius and medium/jumbo frets.
(There are exceptions to both those statements, but they're pretty much true)
After that, take your pick of hardware, pickups, colours etc. I don't think there's anything with a really thin neck (Ibanez Wizard style), but you should be OK with the modern C shape.
