I have used OpenShot Video Editor for editing Videos for upload, and Audacity for capturing and editing audio.
Both programs come free on the Linux 19.2 Cinnamon operating systems that I use. Also available for download online, for Windows. Open Source so it's free.
Kevin Stratvert has one of the best video editing tutorials for the OpenShot video editing software.

Kevin is the one I learned from, easy to follow along, and well explained.
