Thank you for your quick response!
I get it but how should I use the Cache? I understand that there's a PSR CacheInterface which doesn't provide this functionality. Should I use "Spiral\Cache\CacheStorageProviderInterface" instead? I'm a little bit confused about Cache/Storage being together.

This was the first approach:

final class RedisProductPriceRepository
{
    public function __construct(
        private readonly Psr\SimpleCache\CacheInterface\CacheInterface $cache,
    ) {
    }

    public function save(Product $product): void
    {
        $this->cache->set(
            sprintf(
                '%s_%s',
                CacheKeys::Products->value,
                $product->id(),
            ),
            igbinary_serialize($product->values()),
        );
    }
}

But now I'd like to force always to use igbinary. I appreciate any help.Thank you again!

All you need is just

$this->cache->set(
    key: 'key', 
    value: ['some' => 'data'], 
    ttl: 3600
);

Values will be serialized authomaticaly
