I need to replace a few windows around the house.

The problem is, even using correctly-sized windows (35.5" width in a 36" opening), I end up with gaps that are too big to be caulked over or look awful.

The originals have these narrow aluminum strips that cover the gap, but I I've searched ad nauseum and can't even figure out what they're called.

Hard to tell exactly what's going on from the close-up pic. Is the 36" width measured on the outside (brick) side or inside the house? The window has to fit in the framed opening of the wall, if the brick opening is much wider than the framed opening a filler strip is added on the brick side, typically referred to as a jamb extension. This assuming your wall is wood framed with brick on the exterior.
 
Picture is a little rough to get a good handle on situation.Maybe siding contractor can bend up what you need.


The piece I'm referring to is just left of the caulk line.

It's channel aluminum with a lip that overlaps the window frame and rectangular channel that covers the gap between the frame and brick.

It's about 3/4" wide and runs the full length of the window.

I'm still uncertain of what I'm looking at. Is the window at a corner of the house, or is that brick on the outside.

An aside: does the aluminum frame have a thermal break built in between the outside and inside? My biggest beef about double pane window installed here is that the frames are clearly solid straight through, so do nothing to isolate the inside of the house from the outside heat.
 
Possibly a nailing flange?

My thoughts also.

If these are original, new constructions windows with a nailing flange that has been bricked over, sash replacement is the only reasonable option.

If no nailing flange and the entire window can be removed, vinyl replacement windows can be custom built to fit and pvc trimmed if needed for a rot-free finish. Not cheap or easy but cheaper and better (IMO) than wood.
