Form 8938 filing requirement

I am wondering whether I should file form 8938. This is really a question of which threshold I should follow, since I don't really know whether I live in the US or not!!

 

I am a green card holder since I entered the US mid October 2022 (before that, I had no US tax obligations whatsoever). Then I left the US back to Europe where I currently live on 3 December. Here are my questions:

1. Do I live inside the US or outside for tax purposes? The natural answer for me is I live outside, because I haven't fully moved back to the US. However, in 2022 I have spent in the US more than 35 days (365 minus 330), so I fail the physical presence test, and I don't really think that I am a bona-fide resident of country X in Europe because I moved there from another European country in February 2022 (so not a full tax year), and I also plan to move back to the US. So which threshold of reporting applies to me?

2. My tax obligations start mid October.  No income before is reportable to the US. Does this also apply to foreign accounts? Do I need only to consider the highest amount from mid October to 31 December to judge whether I trigger the threshold, or do I apply it for the entire year anyway? Same question goes for FBAR (which I know I will have to file because there's only one, very low, threshold!)...

3. This is a somehow related question: what address should I use on 1040? My European address or my US address? And does this have any significance as to what my tax obligations would be or whether I could claim Foreign Tax Credit? Or is this simply an address for contact if they need to reach me?
