TL;DR: “We have X-references at home” Cross-references in Org mode are not as well developed as its (relatively) new citation system. Org’s built-in linking system is fairly comprehensive and exports to all formats well enough. But if you’re coming to Org from LaTeX, you might prefer something more familiar and oriented towards the label/references mental mapping than the anchor/link system. Over the decades, I drifted into Org mode from writing LaTeX, and brought along RefTeX support.
