Our go-to example for driving these displays is the Alpha Clock Five. There is example Arduino code there which you may be able to use as a basis for other projects. You can also look at the hardware documentation to see how we drive the different length segments and decimal point.
Adafruit likely has example code for the various components that you linked to– their learning system has lots of resources.
