It might be easiest to say what exactly your current situation is - and ask for advice on getting from that point to where you want to be. I've gone from UK ATPL(A) to FAA ATP and would be willing to advise. It is complicated and there's no simple answer to the scenarios you've given.
It sounds like from your scenarios you're at the start of the whole pilot journey?
* US military aviators and graduates of certain aviation programs qualify for reductions in the 1500 hour requirement
I'm not able to privately message you, but would you be able to share your experience with the conversion process from a UK ATPL to the FAA ATP, and the subsequent job search in the States? Many thanks!
