TLDR: You don't have to change anything more. You could also input your quad dns server in system - settings - general and uncheck using the ISP dns servers again if you want.
For anybody that comes after: Using wireguard with hostnames and forcing the OPNsense to be a DNS client to Adguard itself can be a bad idea due to race conditions during boot.
