I would look for the prototype styles of switches on the internet. Your scale is large enough that what works for the prototype would work for you.
There are pro's and con's to each type, from a stub switch, to the notched stock rails, to the tapered and undercut point rails.
Also, some variations in frogs too, although you might not want to run flange bearing frogs unless you can standardize flange depth on all wheels.
In addition, I doubt you would utilize any of the super high speed turnout designs, some have moving frogs, but a lot of complexity.
Stub switches are very easy to build, but not the smoothest, i.e. not best for mainline, but more in a switchyard, or engine yard.
It's an interesting subject, and might also be influenced by your rail material, i.e. steel vs. aluminum, although most all new construction seems to be aluminum.
Best of luck!
