Screen Recording software

I've found it very helpful in the way I learn to create reference material by recording meetings and code alongs that I have with people. This has become pretty inefficient with so many different platforms to have video/screen share meetings with?

Has anybody found a really nice streamlined, easy to use application that I can easily capture a screen recorded video that includes the system output of my MacBook Pro as well as my mic that comes in through as a seperate audio device?

QuickTime 'screen recording' does EXACTLY what I would like it do, but sadly doesn't have the feature built in to capture my mic audio and system audio at the same time. Ive tried setting up and aggregate device and do some internal wiring with getting the audio to record correctly, but its a major pain and very confusing.

Zoom does exactly what I want, but I don't always get the option of using zoom to do my screen recording.

I know there has got to be something good out there. But I've had difficulty finding it.
