Install CMB2 Field Link.

Create a metabox in the usual way.

Add a link field:

$cmb->add_field( [
  'name' => __( 'Link Field', 'cmb2' ),
  'desc' => __( 'Create a link with some attributes.', 'cmb2' ),
  'id' => $prefix . 'link',
  'type' => 'link',
  //'repeatable' => true,
  ],
);

link field example

Accessing the link

Retrieve the post meta:

$link = get_post_meta( get_the_ID(), $prefix . 'link', true );

print_r( $link );

// Link Attributes

Array
(
    [href] => https://wordpress.org/plugins/CMB2/
    [text] => Download CMB2
    [class] => awesome class
    [rel] => nofollow
    [title] => Click me to view CMB2
)

You can build your link like:

print '<a href="' . $link['href'] . '" class="' . $link['class'] . '" rel="' . $link['rel'] . '" title="' . $link['title'] . '">' . $link['text'] . '</a>';

It's a good idea to test for each property before just trying to print.
