Fujifilm xf 30mm f 2 8 r lm wr macro vs sigma 30mm f 1 4 dc dn contemporary?

These two share a focal length and a similar full-frame equivalent (about 45mm on Fujifilm X), but they do different jobs.

The Sigma 30mm f/1.4 DC DN Contemporary is the one I'd pick for most people. It's a cheap, sharp, fast prime. At f/1.4 its depth of field is about that of f/2.1 on Fujifilm X, so it's good for low light, people and food. It also fits many other mounts if you switch systems later.

The Fujifilm XF 30mm f/2.8 R LM WR Macro is the choice if you shoot close-up subjects and want a dedicated macro lens. It's slower at f/2.8, with about the depth of field of f/4.2, and it only fits Fujifilm X bodies.

If you're starting out, the first lenses guide explains why a fast standard prime is a good early buy.
