That a WordPress site can became a Fediverse entity is awesome! We seriously do need more non-Mastodon things in Fediverse, or it will completely turn into Mastodoniverse, defying half of its reason to be (the other half being the federation part).

I also feel the urge to mention Bridgy Fed that enables any webmention-capable website (not necessarily a WordPress one) to connect to Fediverse — yet another option one might consider.
