The Surfshark 7-day free trial version gives you the complete service you can have as a paying member. So, as far as features are concerned, during the seven days of the free trial, you can do whatever a premium member can do without any cost. In other words, since the free Surfshark version is the same as the premium version, the answer is yes, it's good enough to unblock Netflix, too. In addition, this VPN works well with other media platforms, including geo-blocked content. So, if you're a Netflix enthusiast, Surfshark is the best you can do at the minimum possible cost.
