There are three grades with OBOD, and I've done the first of them. I'm not sure how you could embark on a journey like this and not benefit personally, but one thing that stands out about how OBOD does things is it is not merely about personal benefit as it is with some paths of contemporary Paganism. There's an emphasis placed on being of service and aiding something greater than yourself.
I just wanted to agree with you here, and add that if anything the Bardic Course is really about finding the inner you and bringing the fruits of it into the world. I think most of us are naturally helpful creatures provided that we remove the obstacles from helping us do that. Here's what the OBOD website says about the grade:
"The aim of the Bardic course is to help your life flourish and blossom - to help your Soul express itself fully in the world. It does this by helping you discover the sources of your creative power so that their gifts can flow fully in your life. In addition, it teaches the fundamental skills and techniques of Druid spirituality: the use of ritual, of sacred space, of the circle, the directions and elements. During the first year, you are taught thirteen rituals in addition to the eight Druid seasonal ceremonies. These rituals help to attune you to the natural world, to the rhythms of the earth and moon, the sun and stars. And as they do this, they help you to access your Deep Self, your Soul - that part of you which feels at one with all life." - http://www.druidry.org/join/membership-orders-training-course
This may or may not be important to you, and honestly, at the time when I started the intro, I thought I wasn't that impressed. I wasn't immediately into Druidry or anything myself -- originally I read The Druidry Handbook by John Greer and that sort of had me taking the whole thing a lot more seriously. I picked OBOD for several reasons:
1) They are more tolerant of divergent beliefs and do not have an operating dogma, and care even less what I believe personally. They are teaching in an experienced manner, so my experience matters more than what the group dictates.
2) Course work is more newbie friendly than other groups (I'll get to this later)
3) I am not expected to do a lot of academic research that I am not qualified to do. (More on this too..)
4) OBOD is ALOT larger. This means it is easier to find help when you need it, and the course has been through more students. The production value is high.
I researched AODA, and ADF as well. I found that they required a bunch of work on research which I wouldn't even understand how to begin. I also did not see that as relevant as I wouldn't be qualified to judge the information at this present time. Secondly, both of those organizations are proper churches vs being mystery schools. The difference is that churches have dogmas and there not as many things to argue about. OBOD allows my "Druidry" to change as I do and the other groups might be focused on recreating historical Druid practices, insomuch as they can, and not so much allowing me to come to these revelations myself. AODA and ADF seem to also require a ton more time and work, and maybe you don't have that extra time or want to be that deep in it yet. (I found this was a problem in my own case...)
Anyway, based on this info I can assure you that you probably won't learn anything you asked about in the first year @Faronator in OBOD. In the other groups, you have a better chance but you are also talking an exponential volume of extra work.
