Everyone’s browsing is different, and that is expected. I added several third-party blocklists to both uBlock Origin and Pi-hole. Running Linux, I never see Pi-hole block much of anything. uBlock Origin blocks tons of stuff as expected. Please note that depending on your browsing and which third-party blocklists you add, perhaps all of them like I did, you will probably need to learn how to manually unblock specific elements/assets in uBlock Origin using the logging. It is not difficult, but some sites can be mildly annoying. If you like tinkering with blocking everything you can, and then opening up what you need (whitelisting), you may enjoy this.
If someone is new to third-party blocklists, I would recommend starting with the two HaGeZi lists. BadBlock+ and some of the others can be very restrictive.
My Arkenfox (hardened Firefox) DNS bypasses Pi-hole going directly to Tor’s DNS resolver. I configured uBlock Origin (Hard Mode) to perform blocklist blocking and cosmetic blocking (element picker) while using temporal graylisting for Javascript, etcetera.
