I think what the OP is having a hard time with is figuring out how to model the characters that exist in his/her imagination. How can he/she modal a character who is a master of drill and ceremony? He/she can take the soldier background and Perform skill, but that also makes his/her character an equally good actor, which the character is not.
When the game had 40+ different skills (3.0 edition), players were complaining they were too many and started asking for some skills to be merged (3.5 edition) then merged even more (5th edition), and even today some people go around saying to keep merging them or just give proficiency to all checks with some of the 6 abilities. There are even a few who say 6 abilities are too many and only want 2 for brawns & brains.
This is a false problem. You want a juggler that is not an actor? Well, juggle more and act less!

It is a players' failure to believe that the numbers on their character sheet define who they are more than their behaviour.
