The way that I came to terms with Ada strings (coming from Pascal) was to first, learn about the three different kinds of strings; second, pretty much forget what I knew about Pascal strings; third, realize that most of the built-in Ada functions require a fixed-length string as arguments; fourth, work with mostly unbounded strings until it is necessary to pass them to a function, at which time use To_String (and To_Unbounded when going in the other direction); and finally, write all your own subprograms so that they too use fixed-length strings. I rarely or never use Pascal-style strings which are most closely mimiced in Ada by bounded-length strings.
When I started Ada, learning about strings and subtypes were the two most important concepts that got me writing basic code effectively. (I could add, Ada's most excellent approach to variable-length arrays.)
