The one and only thing a VPN does is that it switches your IP to another. It has absolutely nothing to do with privacy or security. An IP-address is just a single metric among hundreds that are used on the web to track users. IPs are also typically not equal to a user. It is common that an IP is a set of users and IPs often change when it comes to consumer ISPs. VPN makes sense in TCP-scenarios like Bittorrent but for web it is pretty much useless in itself.

If you use any currently standard protocol such as wireguard, openvpn, IPSEC with Suite-B ciphers you are getting 'enhanced-privacy'* from eavesdroppers on your local network, which eliminates alot of low-tier/easy MiTM attacks. A two-layer/double tunnel is pretty-good for mitigating against most commercial data collection by eavesdroppers. (Though your tunnel-exit/last-VPN-hop, (varying by client-destination protocol), and the destination IPs/sites will still be able to collect data of course). *Consider privacy a vector. Suite-B ciphers are not perfect, letalone their freely-available implementations.
