Lard or the fat can be made into Lardo - or cured pork fat (Italian name). This is done without rendering it. It's remarkably tasty. There are many versions of this around the world.
Lard can be 'cleaned' to remove much of the pork flavor too, and then is usually for nearly everything. You can look this up, but is mostly a process of boiling it in water. I personally don't mind some pork flavor.
It can be used to help start fires in your fireplace or woodstove, but here I would not use fresh good quality lard, but old rancid lard.
Great for seasoning cast iron. I've tried other things and now specifically collect pork fat for this purpose. It works better than other fats (well beef fat works nearly the same).
It can be used as a lubricant when using tools. Some old-time devices (like cart wheels) were frequently lubricated with lard (often mixed with other ingredients). It can also keep some tools from rusting.
It was used medicinally and cosmetically and mixed with herbs and other materials and used as a balm, salve, or poultice.
