The problem with modern stat blocks is that they include a lot of information that will likely never come up. And they take up a lot of room. For monsters in the MM where they will be used again and again, that is fine. For the mayor of a town or a guard, not so much.
Also much of the stat block is calculated material. All you really need is the class(s), level(s), feats, skill ranks, and equipment. You can calc the rest. For a guard, precalcing spot, listen, AC, attack, and damage might be good, but I can do most of this on the fly.
Barek, Fighter 4, S15,D11,C11,I10,W10,Ch10, MW Longsword, MW Breastplate, Alterness, Weapon Focus, Weapon Spec, Improved Init, Iron Will, Spot 3r, Listen 3 r, Intimidate 2 r.
Init +4, AC 15, HP 28, Attack: +8 (d8+4), Fort +5, Ref +1, Will +3, Spot +5, Listen +5
So the first part is all you need, the second useful stuff is calculated for you. I would be happy with the last line, it has all I really need.
I realized that I don't roll hit points, if you do you would need to include it in the base part.
