For the text selection, see my other comment in this thread and turn on the "Enable line wrapping selection". For the command window size and scrollback buffer, I've always had good luck - in Windows 10 and older versions - by setting the options in the Layout tab of the command prompt property pages. I also use the Font tab to select Consolas. It is true that some programs that open their own command window don't follow these settings, but I usually open cmd.exe and go from there.
