All of the suggestions here are good but I would not put too much stock in where you get your DNS from if your reasons are for privacy. If anything, using anything beyond your ISP’s DNS could decrease your privacy, because now you are giving info to 2 providers (DNS and ISP)

No matter what DNS server you use, your ISP can see every single IP you connect to and doing reverse lookups is extremely trivial for them of course.

My advice is to use a good VPN provider. Any reputable one will also provide its own DNS servers as well.
