Most forum CMS are pretty terrible SEO wise. They are super fast and efficient when talking about forums, and they feel confortable to be use, like this Xenforo in Babiato. But for SEO purposes they are simply terrible (this is why for my little forums I always choose bbPress straight away, although it is not as powerful as Xenforo).
If you want a forum for SEO, move away from any forum CMS naming Xenforo, phpBB, SMF, vBulletin or IPS.
Still, if you want to do something SEO wise. Ozzmodz could be a thing that solves like 30% of the whole issue, but still s***t compared to what you could be doing with bbPress.
Conclusion: If you care about SEO and Xenforo, try to implement what you need manually. Xenforo by itself has some elements integrated by default, but pick a good SEO analyzer like Sitebulb and solve the issues integrating many mini-resources for each single aspect it fails.
Also beware of WPO issues, that you may find some (like Lazyloading and script deferring)
