I've found that even on the index you can't really tell the difference between 20p and 1080p, so i just use 720p encodes. Bitrate is up to you and your viewers's internet speeds. I stick with CRF 28, which is about 3Mbps and it looks fine. you can use -maxrate 3M -bufsize 3M to hardcap it if you have buffering issues.
