There are a few interpretations to your question. If you mean for a company or homelab, yes, you can use a VPN and you internal systems are more likely to be safer from the outside, because malicious actors need to figure out how to access the internal network before being able to access the internal infrastructure. VPN prevents the internal infrastructure from being open to the internet, most of the time. Because of how VPNs work it also prevents your users from getting credentials stolen from a public WiFi they decided to use that day, assuming you encrypt the VPN traffic (see next section). That being said, if you are wanting a VPN for daily life, the areas you increase protection would include Going on public, or less trusted WiFi networks. Most public VPNs that advertise security will provide encryption to their servers before sending their traffic to the place you want it to go, Some people use VPNs to prevent their ISPs/telephone providers from knowing what kind of traffic goes to/from you, And lastly, some people just use them to change where it looks like the user is located, since most places use the location of an IP to determine where someone is located. Maybe there are more things, but these were the main that came to mind. As for "which is the best"... The answer I give is "which is better for you?": Some people will say "make your own!" is the best. Most people can buy a VPS from a cloud provider and setup something like wireguard on the server to hook up to a phone. You know the provider of the VPN will not snoop on your traffic, because YOU are the provider; you will have as much internet as you pay for, not as much as the VPN provider has at that time on a server; and you likely will not have as many places blocking you for being on a VPN (as those places block IPs from VPN providers). The benefit of the providers,  however is a much larger selection of IPs and different locations to easily connect your VPN to, they maintain the servers, and you will be one user among many who connect to a website (the single IP from your VPS, and it always being you who connects can allow for correlation as to whom is connecting), along with other features sometimes. So, if you are going for security, cheap, and generally works well? Make your own. If you want anonymity, many countries to connect from, and low maintenance? Do a trusted public one. "BUT WHO CAN YOU TRUST! THERE ARE SO MANY!" Yeaaahhhh, I generally just look here and pick one: https://www.privacytools.io/#vpn Mullvad tends to be regarded as the best option for people who do not make their own and for minor reasons such as "you can send cash" and... something about how they handle usernames, but many people prefer ProtonVPN.  I'm sure the others in the list are fine, too.
