Both third party developers and Apple have increasingly become terrible at respecting the user’s disk space. Recently my iPhone started crashing as it ran out of space. I found that Apple Maps was using twenty gigs. Fortunately the fix is simple as the issue is widespread and it has become the first search result. https://discussions.apple.com/thread/256084682?sortBy=rank

If you have 512GB I don’t think you really experience the worst of it. A lot of bugs are just Apple creating humongous temporary files before they are deleted as they age. Unless you check every day you don’t really know how much is really being used. You don’t really experience these crashes, and you have no skin in the game to make an informed comment.
