Most consider the industry standard for video editing to be Adobe Premier Pro CC. This software is generally the go-to for large studios, and most video editing courses will teach you how to use it effectively.
Final Cut Pro X is also popular in video editing. However, this program is for macOS only and is significantly weaker than Adobe Premier Pro CC.
DaVinci Resolve and Fusion have also gained traction recently and have seen more use industry-wide in major productions. Its versatility and power are virtually unmatched, making it one of the front runners in dark horse software for video editors.
Avid Media Composer is also popular as an alternative choice to Adobe Premier Pro CC and Final Cut Pro X. Its compatibility with plugins makes it easy to build a compelling suite that perfectly suits your preferences.
