My 2006 Sienna had not been driven for sometime as I have been traveling with work, so the battery was down. In a rush today (15 degrees!), I reversed the jumper cables. I realized it quickly, and successfully jumped it off, but in the process I blew the throttle control fuse. Just a 10-amper, so I replaced that, but I'm curious if the "check engine" light is telling me that I may have also blown the alt fuse, which I understand is common in this scenario. If it is blown, would there be other symptoms? The car cranks fine, and all other lights and controls appear to be working.

There is a 100 amp main fusible link, but you would probably have no electric power at all if that was open.
If the vehicle is within the 36 month, 36,000 mile basic warranty, my recommendation is to bring it to a Toyota dealer for diagnosis rather than speculate on which of hundreds of codes could be stored.
Some of those CEL's require that the condition occur several times BEFORE the CEL comes on again.
