Longer arrow makes for smaller gaps if you gap shoot. Other than that, no advantages that I can see. They're also a bit more unwieldily. If you use a bow quiver, the nock ends of the arrows are much more likely to stick in the dirt when you lean your bow against a tree. Because they're longer, any bow movement on stand is amplified. It also takes more movement to draw the arrow from the quiver and get it on the string, regardless of what kind of quiver you use.
I cut my arrows to one inch longer than my draw length and tune them to the bow with point, insert and adaptor weight, and sometimes side plate adjustment.
35-55s may be a bit stiff if you cut them to 28 inches. But, you may be able to load the front end enough to get good arrow flight and still have a modest weight arrow. Only way to know for sure is to try one out. Good luck.
