I would recommend starting by figuring out why you personally would use a VPN. What specific threats are you facing? What can a VPN help you mitigate? The marketing (“makes you private online”) is mostly nonsense, you just move your implicit trust from your ISP to the VPN provider. For example, when you’re going things online your local government doesn’t like, a VPN may not mitigate that risk.
