You can modify your existing code to use the cursor shape codes for a vertical line (or "I" cursor) and a block cursor instead of the beam cursor shape. Here is an updated version of your code that will show a vertical line cursor in insert mode and a block cursor in normal mode:

# change cursor shape for different vi modes
cursor_mode() {
    # See https://ttssh2.osdn.jp/manual/4/en/usage/tips/vim.html for cursor shapes
    cursor_block='\e[2 q'
    cursor_vertical='\e[3 q'
    function zle-keymap-select {
        if [[ ${KEYMAP} == vicmd ]] ||
               [[ $1 = 'block' ]]; then
            echo -ne $cursor_block
        elif [[ ${KEYMAP} == main ]] ||
                 [[ ${KEYMAP} == viins ]] ||
                 [[ ${KEYMAP} = '' ]] ||
                 [[ $1 = 'vertical' ]]; then
            echo -ne $cursor_vertical
        fi
    }
    zle-line-init() {
        echo -ne $cursor_vertical
    }
    zle -N zle-keymap-select
    zle -N zle-line-init
}

cursor_mode

This updated code sets the cursor_block variable to the code for a block cursor, and the cursor_vertical variable to the code for a vertical line cursor. In the zle-keymap-select function, it checks the current keymap and the argument passed to the function to determine whether to display the block or vertical line cursor. In the zle-line-init function, it sets the initial cursor shape to the vertical line cursor.
