An electrician ran some new wires and had to bore through the floor joists. In doing so, one came very close to a knot in the wood. The floor above squeaks now as a result, where it didn't before. This is probably just a minor annoyance but I'd like to fix it if possible. What options do I have, given the electrical wire running through it?

I'm not convinced that this is causing the squeak. The amount of wood that was removed is trivial. I'd investigate further first. Some glue and/or shims or the tightening of a fastener may resolve the issue. Otherwise...
They make steel repair channels for this type of thing, but they're likely not cheap. Your goal is to restore the tension strength of the bottom portion of the joist. Here's what I'd do as a DIY repair, based on decades of home construction and ownership experience:
Be sure that the gussets pull tight with the first few screws. You can't move them with additional screws. If necessary, pilot through the gussets to the size of the screw threads.
Let the assembly dry for 24 hours before removing the temporary post. 48 hours is even better.
