Short answer

The Sigma 18-50mm F2.8 DC DN Contemporary is a standard zoom for the Fujifilm X mount. It covers 18–50 mm, which frames like 27–75mm on a 35mm camera, and opens to f/2.8. Autofocus is built in.

It mounts on all 34 X mount cameras in the catalog, among them the X-T5, X-T50, X-E5, X-M5, and X-T30 III. Fixed-lens models such as the X100 series are out by definition.
