I am interested
To a large extent I ended up typing a few relevant thoughts in response to @Heyo just above. First off let me repeat, I've got no 'issue' with your belief. You can describe as you will, and your beliefs seem generally positive in terms of world view.
To me, once you move past a general belief, and start picking more particular Christian beliefs, you're moving past the point of being able to claim that God isn't the way we envisage him.
So...belief in God as an agnostic Christian makes some sense, and I can at least build a logical bridge to an interventionist God (since without that you really do seem to be a deist).
Perhaps, for example, you have no personal experience of God, but other people's claimed experiences are somewhat convincing to you, at least enough to nudge you across from 'pure' agnostic to agnostic Christian.
But claiming belief in particular aspects of God...like transubstantiation or the Trinity...yet still claim God is likely not as we imagine him seems tough to reconcile. They are very specific claims about the properties of God.
