I wasted hours at my uni with professors that overcomplicated these search algorithms. You sir saved me big time!

Breadth First Search applies goal test to each node when it is generated rather than when the node is selected for expansion. Therefore, once the algorithm determines shallowest goal node, it stops the search. By following your explaination, the time complexity of BFS comes around in the order of O( b^ (n+1) ). However, if the nodes were to be tested for goal nodes when they were generated rather than when selected for expansion, time complexity becomes O(b ^ n) since whole layer of nodes at depth n would be expanded before goal was detected. b -- branching factor n -- depth of shallowest goal node.

A couple of drawbacks to bring up. Not guaranteed to find the least costed path from S to a Goal State. Also would use a ton of storage to maintain all the current unexpanded nodes. Back in college we had to solve the canibal missionary problem using DFS, because the storage required would grow exponentially if BFS is used.

don't we need to add all the visited letters for that path?

Wrong! Correct Path is: ABDG1

That's the order the nodes get visited in, but the path is the route that the agent needs to take to get to the goal.
