Regarding the line with 6...Bc8, here's a GM encounter I noticed from today. Incidentally 14...Nb4 deviates from ECO, which gave 14...f5 as leading to +=.

I like this approach for black: b6+Bb7 with control of c5 and e4 square and play Ne4 at some point. In the game below black equalized easy (of course black play only for draw in these lines with 6...Bc8)
