From the Handbook, creating a higher order component is a best practice for the WordPress abstraction layer of React.

higher-order-component.js

const { createHigherOrderComponent } = wp.compose;

const withClientIdClassName = createHigherOrderComponent( ( BlockListBlock ) => {
    return ( props ) => {
        return <BlockListBlock { ...props } className={ "block-" + props.clientId } />;
    };
}, 'withClientIdClassName' );

wp.hooks.addFilter( 'editor.BlockListBlock', 'my-plugin/with-client-id-class-name', withClientIdClassName );
