Currently the Paragon Assets only have sound cues for voice lines. There are no sounds included for any attacks or abilities. I think this is a huge missing piece from the release of these assets and will likely hold back attempts by the community to resurrect Paragon. I hope that Epic Games will release these assets in the future.
I did find that Rocket Mania on YouTube has a project that has many of the sound FX from Paragon. I would love to know where the assets can be obtained. Here is a link to the channel that shows the working sound FX https://www.youtube.com/watch?v=C88JHvye2FQ&t=154s.
