I think people are sleeping on Sound Manipulation

Granted there are good heroes that can use sound like Black Canary or Black Bolt but to my knowledge those are the only ones and all they have are powerful screams which are strong but they're many other things you could do with sound.

Levitation and Flight through acoustic levitation, imagine flying through the city and a crumbling building is about to fall in some civilizians and you make the debris float and keep up other surrounding debris from killing more, or keeping your opponents suspended in the air.

Ice or at least cold Generation through thermo acoustic cooling, imagine fighting a fire enemy like Dabi from MHA and converting all that heat into cold.

Shatter objects and creatures with immense vibrations, imagine shattering doors, walls, enemies bodies or parts with strong blasts from the hand. Reminds me of how monks in DND of the Open Hand can send vibrations through the body that deal immense damage as vibrations shred their insides.

Sustained frequencies with different effects. Imagine a low frequency that makes people sick over time, a soothing healing frequency, and boosting frequency. Specific frequencies to debilitate specific species, imagine a dog whistle but it only hurts humans.

Blasts that can propell yourself and others imagine surging through the air like Bakugo from MHA.

Transonic Weapons, similar to mono-molecular edge or high frequency blades imbue edged weapons or bullets with a good enough frequency to slice through anything.

Sound absorption for sneaking around or if the setting is like inFAMOUS in the sense that someone with powers will have to absorb external sources of their element to keep using their power, you'd have damn near unlimited energy especially in loud places.
