The minor seventh chord functions as the ii chord in major keys, the i chord in minor keys, or the iii and vi chords in various contexts (Mulholland & Hojnacki, The Berklee Book of Jazz Harmony). As the ii chord, Fm6/9 is the gateway to the V-I resolution — the most common harmonic progression in jazz. Mantooth emphasises practising ii-V-I voicings in all 12 keys as the foundation of jazz keyboard fluency (Voicings for Jazz Keyboard).
Commonly paired with the Dorian mode when functioning as ii — the natural sixth gives it a brighter quality than Aeolian (Aebersold, Jazz Handbook). As a i chord in minor keys, Dorian is also standard, though Aeolian and melodic minor are used depending on context.
Minor seventh chords typically resolve down a fifth to a dominant seventh chord. Fm6/9 commonly moves to a V7 chord a fourth above (Levine, The Jazz Theory Book).

Fm6/9 is a four-note chord containing F, minor third, perfect fifth, and minor seventh. It creates a warm, dark sound essential to jazz harmony. In Roman numeral analysis, it most often appears as ii (Mulholland & Hojnacki, The Berklee Book of Jazz Harmony).
Common voicings include shell (root, b3, b7), rootless Type A (b3, 5, b7, 9), and rootless Type B (b7, 9, b3, 5). Levine calls these "left-hand voicings" and recommends learning them through the cycle of fifths in all 12 keys (The Jazz Piano Book).
Fm is a minor triad (three notes). Fm6/9 adds the minor seventh, creating a four-note chord with a jazzier, more sophisticated sound. In jazz, Fm6/9 is almost always preferred over Fm.
The ii-V-I progression is the most common chord progression in jazz. Learning to voice the ii chord smoothly is the first step in jazz piano fluency.

Minor seventh chords pair with the Dorian mode. The raised sixth degree distinguishes Dorian from Aeolian and gives the minor chord a brighter quality.
