potential buyer of RBK50 for 3 floor home with router in basement

What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

Looking at RBK50 for basement plus 2-story home.  New ATT fiber router in basement. 2500 sq ft per floor. Looking at Eero, Google, and Orbi.  like the 3-band idea, but worried about signal strength through floors to the main base, as opposed to eero and google units that all talk to each other.  (old guy with a dusty engineering degree, but no modern computer/wireless technology stripes, so somewhat clueless on the acronyms and numbers). 

1) with base unit in basement, should I put satellite on first floor?  will it cover 2nd floor well?

2) why doesn't RBK50 show up as a model.  what is the RBK53?  

3) I have one TV we use is a dumb analog Sony with no HDMI.  If I plug a new Mi Box into an HDMI to three-wire RCA jack converter, will it connect properly with Orbi and then how do I control what it does?  

thanks in advance.
