I tried to set to Google DNS, Cloudflare DNS and check the DNS via dnsleak.

It is still defaulted to my ISP DNS - is the macOS wifi DNS setting broken lately? It used to work.

In the System Setting, select Network and then type DNS in the search window on the left;
that should get you to a window where you can edit the DNS servers

Seems to work for me. I can set different DNS servers and then run DNS queries from terminal; the chosen servers are then being queried. I tested using just WiFi and then I retested using just Ethernet. For both interfaces, everything worked as expected.

One thing to add, browsers can each handle DNS differently, so the system setting might not be respected when using a particular browser. I was just now experimenting with Firefox and wasn't seeing the dns traffic I expected - that is, until I turned off its setting to "Enable DNS over HTTPS" which was set to use Cloudflare.
