:help 'cursorline'
tells Vim to highlight the current line, which may or may not help you keep context as you move around. Enable the feature if you find it useful.
:help 'cursorcolumn'
is basically the same but for the current column. Again, enable it if you think it is useful to you.
Those features differ from visual mode in that a) they don't require a conscious effort from the user for the highlighting to take place, and b) they are not related to editing.
There's no such thing as :help 'cursoropts'
in Vim.
If you want to change the shape of the cursor, this site has plenty of relevant threads: https://vi.stackexchange.com/search?q=cursor+shape.
