Recommend a pair of routers for my fixed wireless setup

Hi All, Im looking for recommendations for what do buy for my setup.I have two locations, a house and shop. between the house and a shop, there is a fixed-wireless solution already in place, a pair of ubiquity fixed-AP satellite dishes that are paired together. They function exactly like one (extremely long) ethernet cable. 

Essentially, im asking what you would buy if you had two locations that were (effectively) wired via ethernet together that are really far apart. So im not looking for a repeater (since I already have a solution in place), but I need good wifi at both locations. The house is two-story 2400 sqft, the shop is 1800sqft one-story metal building. 

I was considering getting a RAX120 for the house, and maybe something smaller like a rax50 for the shop, both on the same subnet. The RAX50 would have DHCP and NAT turned off (bridge mode), so basically access point only. My question is, can I manage both of these with the nighthawk app? And would these be solid purchases? 

thanks
