Build it right, sleep at night.
I agree with that. I do usually overweld my parts. I was pretty frustrated by that breaker I did not want to have to weld double the passes again having to flip breakers every minute. So after a couple beers I've decided I'll swap in a bigger breaker and slap a couple more beads down.
You've made the right decision. Rest assured that welding to the thickness of the thinner part is welding it just right. If you welded to the thickness of the thicker part, that would be over-welding.
And you'll have an upgraded breaker for next time! All good.

Show us another pic after you've finished the triple run fillets to complete the throat thickness.
Since they are fillets on both sides they should add. 1/2" fillet + 1/2" filet = 1" total - more than plate thickness, so he should be good. Plug welds are extra insurance.
You'll pull the frame into before they welds break.

I run the same plug, and I have wired the circuit with 6 gauge conductors. My breaker is a 100 amp breaker. I can run either of my welders wide open up to the duty cycle and the plug and wiring never gets warm. The building code allows for over rating the breaker for a dedicated welder circuit based on duty cycle. It has never been clear to me if that applies to the plugs as well. But in actual practice it has never been a problem for me.

The one plug I use is right under the breaker panel. So to swap in heavy gauge wiring I'd only need 16" or so of wire. I'll definently do that if I ever need more than 65 amps
I’ve welded lots of material like that in the past.
Nothing wrong with using 045 duel shield for that. If your burying slag inclusions, your not set up properly or your technique is bad. Dual shield penetrates much better than solid wire mig. Forget solid wire mig for this.
7018 will be good also. Size of the rod to use just relates to how long it will take you to complete the job.
I would probably do it with a 1/8 or a 5/32 rod.
I’d want to put atleast an 8mm fillet weld on that, maybe even 10 mm fillet weld if you want to over do it a little to be sure.

NEC 2020 Article 210.21(B)(1) exception 2
It allows you to size the receptacle based on the conductor ampacity not the breaker size which is 200% of I1max
