I use Open Broadcaster Software (OBS for short), which is free and can both record and stream, even simultaneously.
You can have multiple input sources such as multiple monitors, webcam, text/graphics overlay etc.
For live streaming I usually go with around 1800-2000kbps for 30fps video with x264 codec and 128kbps stereo audio with AAC codec.
I have very bad experience with the NVENC (nVidia encoder) codec because as soon as there's any motion, the image just breaks apart and lose all detail, as if it's very bad bitrate even though it's clearly not.
As for recording, I tend to use about 8000kbps if I record at 60fps and 4500kbps for 30fps. That's usually enough.

I can actually give some guidance regarding some of the pointers that you listed.
On Youtube and TwitchTV, both recommend a minimum of 3000kbps (~2.9-3.0Mbps) to stream at 1080p. TwitchTV caps out your data speeds at 3250kbps. It use to be around 5Mbps before TwitchTV changed things around a few years back (due to people complaining that their net couldn't watch streams at such a high bitrate).
Where as YouTube will accept all the way to 10Mbps, see: https://support.google.com/youtube/answer/2853702. Why do I say 10Mbps when the 1080p60fps only says 9000kbps? That's where YouTube currently caps out the stream feed bandwidth, not the values listed.
I currently use this when recording locally to a SSD.
I recorded this the other day to make sure OBS was recording decently. Lots of colors and movement generally will show out the minor details having issues. If you observe, the reds are always blurry. That is simply how the encoder functions.
That video is of the settings above.
As for the nvEnc, you can't stream or record out of the box with its default settings, you have to modify it so that it looks decent in quality.
