Aqara U200 vs - Nuki Smart Lock Ultra (for apartment - no outside equipment)

Hi guys.

I’m considering to buy a smart lock for my apartment, and I came across 2 options, the Aqara U200 and the new Niki Ultra.

Since this is to be used in an apartment, no equipment should be visible on the outside of the door. I know that the Aqara U200 has a keypad, but I can’t put it outside.

Having that in mind, what should be the best option? To go for the Nuki Ultra, or go for the U200 and just have the keypad inside the house without using it?

2 doubts: - the U200 works without the keypad outside, correct (I’ll unlock using the app or Siri)? - If I have the keypad attached on the door but from the inside, will I be able to unlock the door from the outside using NFC?

Thank you for your help.
