Toyman- Different plastics are, well, different...so it's risky to generalize.
Of the products on your list, I've never had any staining issues from 845. NONE. I use it on black plastic and other such surfaces all the time, just did the textured black roofrack and the black plastic antennas/trim/etc. of the Denali XL with it. When it finally *fails* it'll sometimes show white staining, but once you clean the surfaces up and reapply it's good as new again. And that failure won't happen for a good long time. Of the stuff on your list that'd be my choice, but again, I've never done a Jeep so I can't make any promises.
I've *very seldom* had problems from #16 but I use a W-O-W-O application with it in this case.
I wouldn't *expect* a problem from #26 or the AW, and I'd be pretty confident about that...but it's just a guess.
I can't even hazard a guess about the others, but I wouldn't try the NXT myself.
