I'm installing a new floor register that needs to be wider than the existing hole, and the score-and-snap method just won't cut it for my needs. I'm considering a circular saw or perhaps a Dremel saw with a wood/plastics blade. Would that work? I'm aiming for clean, straight cuts because the edges will be visible, so I want to avoid any chipping or melting of the LVP. What have you all used in similar situations?

An oscillating multi-tool can also work wonders for getting a straight line. It's pretty straightforward once you get it going.
Honestly, I've used various miter saws with whatever blade happens to be on them without major issues. A blade with a higher tooth count might be a bit better if you're looking for a cleaner finish.
I prefer using a jigsaw for cutting LVP. They have laminate blades that work really well for that material. A good carbide blade is key, and just keep the oscillation speed low. Setting up a fence, like a 2x4 with double-sided tape, helps keep your cuts nice and straight.
I've had great success using regular saw blades with my chop saw for LVP, though it might dull the blade a bit faster. Just be sure to go slow and steady for the best results.

I can't go the jigsaw route since I'm limited to a specific depth on the cut.
