Configurations and good practice advise

[meazz1]

I fairly new to Opnsense and working everyday to customize Opnsense to my needs and preferences. I used EdgerouterX previously so my knowledge is limited due to most basics are already enabled out of the box in Edgerouter setup.
My home network consists of 6 or 7 devices hard wired to a 16 port switch and an Unifi AP-AC Lite as wifi access point. A Pi Hole as my DNS and Ad blocker.

Well, here the questions:
-- Is there a pkg/plugin to take place of the Pi Hole in Opnsense?
-- if I have to use Pi hole as my DNS where in Opnsense GUI do I set that up? I'm confused, I see an option for unbound dns, dns resolver, dns server with gateway etc.
-- sunnyvall3y sense plugin, is it an over kill for home user?
