Software recommendation for video editing

Hi
I am planning to start my YouTube channel for Linux Tutorials in my local language. For this purpose, I have to learn few things like:
1. Video Editing
2. Image Editing
3. How to insert images, banners, thumbnail inside a video
4. Fade in and fade out effects for video
5. Inserting background music etc
I heard that kdenlive is good for video editing, but I haven't tried it yet. So, kindly recommend software which can do these above mentioned things for me.
Thanks

kdenlive is basically the goto.

openshot is another option.

lives

cinelerra

or stay on the command line with ffmpeg.

Most of the non-linear editors (NLE) can do effects like fades. Otherwise various ways to extract frames to images and create effects. With gimp, imagemagick, netpbm, and other options. Just be aware of the various formats and that 30fps really isn't 30, but 30000/1001 aka 29.97 frames per second. The default for ffmpeg is 25 fps unless otherwise overridden / specified. Plus other aspects of videos like color space. It's a heck of a rabbit hole.

I will prefer GUI and user friendly one.

Avidemux for video editing.

Just saying the cli is an option. With ffmpeg + netpbm, green screen stuff in linux was possible more than a decade ago. Just not real time / live streaming.

Thanks a lot

Blender is also an NLE. And apparently a very good one.

all of that is built into blender , but it will take time getting used to using blender's video editing tools
