Basically I use a standard 3/8" contact with screw terminals 95% of the time on residential windows. The only variation is the magnet. For doors, I tend to prefer a 3/4" recessed with 3/8" magnet combination, but there's variations due to construction, etc.
Unfortunately, with 20 years in, there's just as many vinyl window manufacturers out there and styles, but generally speaking, I've contacted just about every one of them at some point.
