Then here is that custom hooked function in woocommerce_package_rates filter hook:

add_filter( 'woocommerce_package_rates', 'conditionally_hide_other_shipping_based_on_items_weight', 100, 1 );
function conditionally_hide_other_shipping_based_on_items_weight( $rates ) {

    // Set HERE your targeted weight (here is 20 kg) <== <== <== <== <==
    $targeted_product_weight = 20;
    
    // Set HERE your targeted cart amount (here is 250)  <== <== <== <== <==
    $targeted_cart_amount = 250;
    // For cart subtotal amount EXCLUDING TAXES
    $passed = WC()->cart->subtotal_ex_tax >= $targeted_cart_amount ? true : false;
    // For cart subtotal amount INCLUDING TAXES (replace by this):
    // $passed = WC()->cart->subtotal >= $targeted_cart_amount ? true : false;
    $light_products_only = true; // Initializing

    // Iterating trough cart items to get the weight for each item
    foreach( $package['contents'] as $cart_item ){
        // Getting the product weight
        $product_weight = $cart_item['data']->get_weight();

        if( !empty($product_weight) && $product_weight >= $targeted_product_weight ){
            $light_products_only = false;
            break;
        }
    }

    // If 'free_shipping' method is available and if products are not heavy
    // and cart amout up to the target limit, we hide other methods
    $free = array();
    foreach ( $rates as $rate_id => $rate ) {
        if ( 'free_shipping' === $rate->method_id && $passed && $light_products_only ) {
            $free[ $rate_id ] = $rate;
            break;
        }
    }

    return ! empty( $free ) ? $free : $rates;
}
