Ah, that's awesome.
How to remove this rusty diff fluid fill plug?

I was going to say heat, then impact. But you got it!
If all else fails cut the rear cover off and have a new one welded on.
I use Mobil 1 75w-140 for about 24 years , several hundred thousand cumulative miles. Using it in vintage Shelby Mustangs and Jaguar XKR’s.
Plenty of rear end abuse, nevertheless no wearing or breakage issues.

Here is a screen shot of a posting I did back in 2020. It discusses the different temps with different gases. Oxy acetylene is best but if you don’t have access to it a Mapp/ Oxy Kit can be had for $100. Good luck and let us know “ The rest of the story”. 
Home made Thermite:
Mix 50:50 iron oxide and [REDACTED]. Ignite with a magnesium strip tucked into the heap of Thermite, lit with a propane torch.
When the Thermite eats it's easy to China through your driveway, the axle will be cool enough to replace with a new one.

Nah, hammering on a slightly smaller 6-point socket and then attaching your breaker bar works a cinch. The trick here is to yank/snap on the breaker bar until the bolt breaks free. No hammers. No impacts, sometimes they can just twist the bolt head off. Slow, steady pressure will twist them too.
Get the handle of the breaker bar in a good spot that you can pull on it like a maniac in a fitness planet rushing through pull ups.

Man....all these guys must live in the south. That is an average looking thing for here in the 6 months of salt part of the country. Actually, not many 2003s left.
And living in sunny CA I hve never seen such a thing.
Guilty.
Get a look at the Youtube channel, "South Main Auto". The fellow that owns it is Eric O. - he works and lives in the north eastern rust belt. Typically a car is done at the end of it's 8th season of salt coated roads. I just watched him fail a car for repair and inspection after putting his "Judge" through the frame of a compact pickup. He fights and strains and has specialty tools to just wrangle the salt rotten cars back into submission and complete the repair.
When a component literally just unscrews like it should? His common response is "Huh, someone must have just worked on this...."
Or:
"This must be like when you work on cars in the South..."
What did the diff oil look like that came out?
Haven't drained it yet.
This.
I have had lots of luck using an impact in these situations as well. I turn the regulator down to about 40 - 50psi, enough to allow it to hammer without breaking or stripping anything, and then let it chug away for a little bit. Of course you do need an air powered impact to do this.
That really does not look bad.
OK, now you have extra incentive to get the fill plug out.

Oh man, you drained it before getting the fill plug out
Not my first rodeo.
