Things to consider before buying? - Xiaomi Redmi Note 4 Questions & Answers

Hello everyone,
I'm considering buying this phone for some time now (Snapdragon).
I really like it overall, I consider it being a great value-for-money device, plus I've noticed great custom ROM support for it (there's even a DirtyUnicorns build which I wanted to try since I've never used it before) which is crucial to me since I don't like MIUI.
Now I wanted to ask hoping for an answer as complete as possible, (especially given the fact that Xiaomis product line and naming is as complicated as it is) what things do I have to consider before buying?
For example, I know that Product Number 2016101 won't support the LTE band I'll be needing in Greece (where I stay) so I should go for the 2016102 one (Global Version).
But other than that,
1) should I prefer the 4GB/64GB model to the 3GB/32GB one or is it not worth it (around 30 euros diff, which is a 16% +)
2) Is there any other info (serial/model/product numbers) I should check on the box?
3) Is there any way to know the sensors types before buying? And if yes which ones should I go for? Would maybe buying from an official reseller assure in any way that I'm buying the best sensors options?
4) For the 2016102 model which is the 4 Global Version, do I have to buy Accessories targeted at 4 or 4X?
5) ANY other possible things to know before buying
Thanks in advance to anyone and everyone that will spend time answering my questions!!!

For #2 I meant like if on the package "product number: 2016102" is listed you can know for sure that this is RN4 Global Version. I was asking if there is any more similar checks I can do.
For #3 I meant if there is a way to know before buying if the camera sensor for example is IMX or the other one, the FP sensor is Goodix or other etc...
Also, for #4 I'm pretty sure not all accesories fit both phones. You can search on xda and find out for yourself. For example some tempered glass alternatives cover the LED notification, some cases cover IR blaster etc.

2)The product number is 201610 which is mentioned on the box.
3)I have added some screenshot of AID 64 please check. And no you can't check sensors info before. As they don't mention on the box.[Check Screenshots]
4) Yes you are right the placement of IR and notification LED are different. i got an universal backup cover from a local store which is for both variant. better you check before buying it. especially in tempered glass.
