What’s the difference between a trim saw and a regular circular saw other than the obvious size and shape? Does the smaller blade produce a cleaner cut? If so, does anyone know the technical theory behind that?
From building boxes and fitting face frames to installing doors and drawers, these techniques could be used for lots of cabinet projects.

I can tell you this, but you probably know it. Those little PC trim saws are darned expensive!
It may be that the drive is such that the blade arbor has far less potential for wobble for the little trim saw, and that, coupled with the smaller blade size, produces far less blade runout, thus a smoother cut.
Have owned a PC trim saw since mid 70's and it works great. Used it for cutting sheet stock on job sites. Well balanced light weight and everyone who has used my saw likes it.
One saw for everything - Skil worm; accurate, powerful and heavy. For trimming? Damn straight. Aim down, and just like the inertia of a Cadillac, it goes smooth and straight.
Popeye arms a welcome side effect.

A trim saw is simply smaller, more maneuverable, lighter and intended for cutting smaller pieces, i.e. trim as opposed to lumber.
A smaller diameter blade can be made thinner for the same stiffness. A thinner kerf requires less power, generates less dust, requires less force to push through the piece and is less likely to cause tearout.

Trim saw is just compact and easy to use for light cutting. The bearings on any decent saw with little side to side play will cut straight with the right blade. High tooth count finish blades for a normal circ saw can produce fantastic cuts. Finish blades also have less "set" so the sides of the teeth don't hog out as much extra wood for blade clearance. A good finish blade will quickly show if your blade is in line with the base of the saw.
