What is the replacement for menu_link_load()? Drupal 7 has menu_link_load() to load a single menu item. What is the Drupal 8 equivalent?
Drupal 8 menu links are now content entities. The equivalent to loading a D7 menu link object would be loading a MenuLinkContent entity. This can be done via the static Drupal\menu_link_content\Entity\MenuLinkContent::load() method.
