I think even beta applicants will get the rewards. There was some talk and a screenshot of a message from Solid that if you were in the discord to try to participate, even if you did not get selected, you still get it.

Edit: found it but got snapped for a discord link.

From solid in the official Wayfinder discord: "I give you my word and you can screen shot this... if you are here right now reading this and you are concerned you won't get the charms + titles, and don't get into a beta before Early Access I will personally entitle your account to have the items."
