The common shapes, written lowest string first: 131113, x33044, 465564, x8688x, x-10-10-10-9-11, x-x-10-12-9-11, 13-11-13-0-13-13, 13-11-x-12-13-11, x-11-13-12-13-13, 13-15-13-13-13-15.

Shell. Root, third and seventh: the guide tones fix the quality, so the fifth is dropped. That is what leaves a string free, so pick a tension to put on top. Fm9 has x8688x, 13-11-13-12-x-x, xx3143.

Drop 2. A close-position chord with the second voice from the top lowered an octave. Sits on four adjacent strings. Fm9 has x8688x, 13-11-13-12-x-x, xx3143, 4858xx, xx5864, x-10-13-10-9-x, x-x-13-12-9-13, 3631xx.

Drop 3. The third voice from the top lowered an octave. The dropped voice becomes the bass, which is why a string is skipped. Fm9 has 3x314x, x8x884, 4x586x, x-10-x-10-9-11, 13-x-13-12-9-x, x6x163, 11-x-6-10-8-x.

Rootless. The root left to the bass player. Frees a finger for a tension. Fm9 has xx1113, xx5544, xx6888, x-10-10-8-9-x, x-11-13-12-13-x, x-x-13-13-13-15, x3x143, x3514x.

Open string. An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful. Fm9 has 4600xx.

Tensions. A shell of Fm9, root, third and seventh, leaves a string free, and the tones that belong over it are the 11 (Bb) and the 13 (D).

The common shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
