Hi! I wanna record programs like video streaming but to recording with edit graphic, and wanna edit the material after recording. I dont wanna upload it I just wanna have high quality videos of me playing. I wanna record in 1080p , 50fps. Now I have a ton of question :D

1. Which one of this (CQP or CBR or VBR) is the better to use to recording? And what the number of bitrate/CQ Level have use?
2. Which one of this (CQP or CBR or VBR) is the better to use to recording while streaming? And what the number of bitrate/CQ Level have use?
3. What the number of keyframe interval should to be?
4. If I have to select Max Quality in Preset?

Hardware: (dxdiag) of my Laptop:
Intel i9-11900H (16 CPU) 8 core
NVIDIA GeForce RTX 3080 16 GB
32 GB RAM
1 TB + 1 TB + 1 TB M.2 SSD
4k UHD

Thanks!

As for understanding
One thing to consider is that if you use different settings for recording vs using same for streaming, then your computer has twice the encoding work to do. So, be sure to do hardware resource monitoring to make sure you aren't bottlenecking somewhere (CPU, GPU, RAM, Disk I/O, etc)

With that said, CBR is typically required for streaming. However, for highest quality recording, VBR or CPQ is often recommended. See lots of recent threads on implications of various settings. In reality, you can go for very high quality recording, but can your computer handle the bitrate involved? Most computers (even really expensive professional workstations) can be pushed beyond their limits, if you aren't careful. So, the question for you is what you your intended final result?
For example, if you are going to record (not stream), then edit, and you have a fast drive to record to, and don't go to far overboard with settings, have at it. But be sure to pick settings which are compatible with your intended video editor.
If you plan to later upload to a provider like YouTube, they will heavily compress the video on their own. So if you have the upload bandwidth, re-encoding to make smaller, then provider re-encoding again is usually NOT a good thing.
so it depends.

There are a number of resent threads going into each setting you are asking about, and results from certain people's testing. your mileage may vary, but at least will explain the various settings numbers
