Variables aren't standard as they're from a higher version of MediaWiki than the heavily forked version Fandom uses. It can be enabled on request, I believe.

Pipes are core functionality of MediaWiki and is its primary argument delimiter. You can't replace it with nothing. While it's sometimes possible they clash with parser functions, that's usually solved with !. There's also the Pipe Escape extension, maybe staff will enable that for you. But this just adds an extra layer of coding in the template, not in the input.
