Is it to avoid your ISP collecting browsing data off you and selling it?
Perhaps using 8.8.8.8 or 1.1.1.1 as your DNS might be good enough.
Is it to watch geo region blocked videos?
Then pretty much any service will work for you. Except that video streaming sites have caught on and blocked hosting provider IP blocks. So that might require you to shop around.
Do you want the most privacy or want to get around blocking?
Then get a VM from a provider and configure a VPN to it. Wireguard works fine.
Want to do something illegal?
Don't expect a VPN to save you.
