The first step should always be your manufacturer. The company that made the hardware you're using either made the cable that goes with it themselves or contracted out to a trusted source to get those cables made. Those cables are designed to work with the hardware you are using. With exception to a recall performed by Apple, cables provided by the manufacturer have all been safely made. If you're ever not sure, buying cables from your manufacturer or a trusted brand is a good way to go in this situation.
If you're specifically looking for third-party cables and want to confirm the quality, you can look in the reviews section for that product on Amazon for detailed analysis or check out Google Engineer Benson Leung's suggestions on quality USB-C cables.
