I'll add the caveat that wood glue is only stronger than the wood itself if you've made a proper joint. If there is any significant gap between your boards that is essentially being "filled" with wood glue, it isn't very strong at all. As long as your joint in tight and clean though, there really isn't anything that performs better, and certainly not for the price and ease of use.

If your joint is janky though, a polyurethane construction adhesive like Liquid Nail is a better choice.

Out of curiosity. Would there be a situation when making a paste of wood glue and sawdust be desireable? Specifically in regards to “filling” small gaps, I wonder if it would be stronger or weaker.

That's a great way to fill old screw holes, like say you strip a screw or something.

But it's not going to bond a good joint that way. Wood glue works best when spread evenly between two square faces, and clamped with sufficient force to make it slightly seep out along the length of the joint.

And ideally avoid endgrain or anything with finish on it- you’re not gonna get wood glue to stick to something painted, clear coated, waxed or pre stained. I can’t tell from op’s description but if it’s gluing new pieces to prefinished, use a construction adhesive or nail in cleats to support the shelf

That's a good (and common) method for filling things cosmetically, but would not be a good structural bond.
