You cannot really extend wifi that distance.. not without fancy gear..
There is no need to because the wifi in the rent house will be totally separate to the home. You just set the same SSID and password as the Time Capsule at home.. and everything will work on wifi in the rental.
You will need a router setup in AP mode, wan bypass or an actual AP.. but the later tend to be more expensive .. it can be just about any brand you like. No need to spend a heap of money.. a cheap decent wifi router will perform great..
It is hard to list models as your market is different to mine.. (Australia).
TP-Link is a brand I like for low cost and reasonable quality. Cheap and cheerful as they say.
The old C2300 was the go to .. but they have likely gone out of production so the next model is AX20. AX1800 in US $110

The specs show one poor aspect.. USB2 port only.. that is really lousy in 2020.. or 2010 even. It does support AP mode.. it even supports time machine to a slow as treacle USB2 drive.. but fulfils the task.
It is good enough for the job.. They even have a lower model.. which is probably OK.. but it will be slower. AX1500.
The cheaper ones are often built on poorer processors so you do lose out.
The EAP245 is a proper AP that would work for you.. but harder to setup.

Better in some ways.. but really designed for more pro level install.. although it says ceiling mount it looks fine to sit on a table.
You can also buy mesh product like TP-Link M5 but it requires signing up to cloud registration in China.. which I personally am not happy to do.
I could have picked loads of other brands.. and even buying a second hand router.. AC wireless will more than likely work fine.. I have used modem routers of both vdsl and cable types and anything wireless.. vast majority will work. Nice if it has AP mode.
Good work running that ethernet btw.
