There are three common, basic categories of film. Slide film, traditional silver halide B&W Print film, & Color Print film. Of those, slide film has the least latitude. Next is conventional B&W followed by color print with the most latitude.
Within those three categories films latitude will also vary. One thing is a given with them...you can not consistently under or overexpose any film by 3 or 4 stops and then think you can repair it in P/S...the information you need just isn't there.
What I suggest you consider is visiting various film web sites and looking for spec's. That will give you some idea what the film is capable of.
