In the “Display and USB Adapters” section your “Minidisplayport to DisplayPort” link is wrong and goes to a USB-C to DisplayPort amazon link instead.

However, here’s a link to the Minidisplayport to DisplayPort adapter: Rankie Mini DisplayPort to DisplayPort Adapter, 4K Resolution Converter, Black that I bought and have been successfully using for the last 4 months (male mini and female DisplayPort).
