I am putting in a truss floor system that has several point loads as well as many cantilevers, which are effectively point loads. My trusses are going through the engineering department at the truss company, but I’m curious what I should expect to see for truss construction at the point loads? Will there be several vertical 2×4’s that “break” the web or do they just specify something like OSB to nailed to the side of the truss to distribute the load properly?
Hope this makes sense.

You won't see plywood on them. And you won't see a bunch of vertical 2x4's that "break" the web - The webbing has to be triangulated.
Wherever the point load hit, you'll see bigger plates and possibly double webs. If you ask the truss company for drawings of the trusses, they most likely wil give them to you.
Check out the attached drawing. It gives you a rough idea of what they might look like. The red arrow shows a possible point load situation.
One thing comes to mind - I've seen several floor truss systems installed with the floor trusses backwards. (And a couple upside-down) If the trusses aren't symmetrical, make dang sure the installer knows which way they go. Otherwise you could be looking at a nasty mess to fix.
Can't emphasize that enough.
If practice makes perfect, and nobody's perfect, why practice?
