To answer my own question, here’s an example of how I achieved it with a Select field, Flexible Content field, and a function that runs on acf/save_post:

function import_layouts_from_a_different_page( $post_id ) {

	// Bail early if no ACF data
	if ( empty( $_POST['acf'] ) ) {
		return;
	}

	// Flex layouts from this page (field_56381b4c8e557 is a Flexible Content field named "Layouts")
	if ( is_array( $_POST['acf']['field_56381b4c8e557'] ) && ! empty( $_POST['acf']['field_56381b4c8e557'] ) ) {
		$current_page_flex_layouts = $_POST['acf']['field_56381b4c8e557'];
	} else {
		$current_page_flex_layouts = array();
	}

	// Determine if there are any pages to import (field_57924308049be is a Select field named "import_flex_layout")
	$pages_to_import = $_POST['acf']['field_57924308049be'];

	// If there aren't any layouts to import, skip the rest.
	if ( empty( $pages_to_import ) ) {
		return;
	}

	// Loop through the (possibly) multiple pages that we'll import.
	foreach ( $pages_to_import as $page_id ) {

		// Get the layouts value from the selected page.
		$layouts_from_page = get_field_object( 'layouts', $page_id, false, true );

		// Add the value to this page.
		if ( ! empty( $layouts_from_page['value'] ) ) {
			$current_page_flex_layouts = array_merge( $current_page_flex_layouts, $layouts_from_page['value'] );
		}
	}

	// Re-set the Layout field value with any imported pages, then continue saving.
	$_POST['acf']['field_56381b4c8e557'] = $current_page_flex_layouts;

	// Clear out the pages to import setting
	$_POST['acf']['field_57924308049be'] = array();

}

// run before ACF saves the $_POST['acf'] data
add_action( 'acf/save_post', 'import_layouts_from_a_different_page', 1 );
