That is a great list of penetrating oils. Having worked in the saltwater marine industry for decades as an engineer, I have definitely come across some seized bolts. I will typically not even try to loosen a seized bolt without putting some heat to it. That may be challenging depending on what you are working on, but may be possible with a small torch, like a small butane torch or something. These are maybe $10 at an auto parts store.
I was able to free up a seized engine with the ATF/Acetone mix after sitting in the cylinders for a couple of days.
The heat/lube combo is good, expansion and then contraction from cooling when sprayed, but be careful about using too much heat and something very flammable. I have used liquid wrench successfully like this. Also tapping on the head of the bolt/screw can loosen things up. Whatever you do, be patient and don't twist off the heads of the bolts.
Best of luck,
