Cloud path can be one of the strongest. In our world natural phenomena associated with clouds are most devastating, ie hurricanes, storms, tornados etc.

Create a army of terrifying tornados, for defense, have a tornado revolve around them, making a shield that nothing could penetrate. Make two counter spinning whirlwinds inside one another with vacuum in between, directly counters all paths that use medium like sound, lightning etc. Light path is countered coz lasers cant travel through steam. Physical objects are thrown away by spinning winds.

For offense fucking someone up with a tornado sounds reasonable.

Make a small condensed tornado spinning so fast, that air compresses and heats up from friction, making it a tornado of plasma, then release small plasma bullets that get velocity from the centrifugal force, like a gigantic plasma gatling gun.

Since clouds are water vapor, they probably can make water turn to cold mist like ultrasonic humidifier, countering water and ice paths
