I cleaned up the positive and negative terminals on the battery and went for a drive today. Neither looked problematic, but there was actually a bit of oxidization between the "layers" of connections on the positive side. Every other connection was tight and clean already. I'd say that made a marked improvement. It's not super hot today (about 70 degrees), but I drove around with the AC on, fan at 4, headlights, foglights, stereo, and rear defroster on. I even moved my windows up and down a few times and had a USB charger in the 12V socket.

I didn't get a real meter out, but the voltage gauge was higher than expected for all of that. There was some light stumbling when the fans came on that maybe dropped to low-mid 12V range on the gauge when idling. If I was moving it was almost always above 13V even with everything. I never had even a single ignition stumble while driving.

Again, this wasn't a high heat day, but even on a day like today, I wouldn't expect it to be so high. It was over 14V as soon as I started it up with no extra accessories turned on yet, and that's more than I've seen on the dash gauge before.
