Seems they aced it
Most wheels come with paddle shifters so no need to buy a separate shifter. You'd need a wheel/base/pedals
The bundles I'd recommend for first time users are as follows
Fanatec Ready to Race Bundle (id personally go with one with a 8nm base, 5nm is quite weak in terms of FFB, although its possible to upgrade your 5nm base to 8nm at a later date)
Our 'Ready to Race' bundles contain at least a Steering Wheel, a Wheel Base, and Pedals - the core components you need to start sim…

(you'd also need to get a table clamp for the base)
Moza Bundle
Experience the future of racing with MOZA Racing's Xbox bundle. Officially licensed by Microsoft, our plug-and-play MOZA R3 offers unparalleled 3.9Nm force feedback, aviation-grade aluminum construction, and eco-friendly PU leather. Elevate your entry-level racing.

(again you'd need to get a table clamp as well, moza's table clamp works with both Fanatec and Moza wheels and is the best one out there)
If this is too expensive then you could just go down the Logitech G923 or G29 route but it's belt-driven and the pedals are quite janky relative to what you get from Fanatec and Moza's starter bundles. Logitech does a direct drive bundle as well btw but it's a lot more expensive than G923 and whilst more than good enough it's probs not on the level of Moza and Fanatec... that said you will have excellent support from Logitech, Fanatec and Moza are both quite small companies in comparison and thus their support can take a while.
Lots of videos on Youtube that go into far more detail
