7m VL cells wouldn't be able to load an ASCM, which would require the 054B to embark traditional slant launchers with their RCS penalty and lack of omnidirectionality. 5m VL cells wouldn't even be able to load an HHQ-16, let alone any of the other missiles.
Depends on the munitions you use (obviously, but hear me out); a 7-meter universal VLS cell would be able to fire all naval weapons currently used by the USN, including the Tomahawk & the LRASM, but would be unable to accommodate Chinese-developed offensive arms.
Lesson of the day: miniaturize your munitions.
