OBS is a solid choice for recording, and I've used it for game capture and tutorials without issues. For editing, Sony Vegas is good but can be pricey, and Adobe Premiere is powerful if you’re willing to commit to learning it. If you're looking for something more user-friendly without a steep learning curve, Movavi Video Editor is a good option.
It’s simple to use and has all the essential tools without being overwhelming. If you ever need to convert audio formats, like M4B files, this M4B converter from https://www.movavi.com/audio-converter/m4b-converter.html could come in handy for audiobooks or podcasts you want to edit.
