Hi Vikrant
Welcome!
Those 52 bottle slots will fill up very quickly and if you’re not careful, you’ll find you quickly have 52 cellar-worthy wines and nothing to drink! Unlike many here, I’d say stick to that wine fridge for as long as you can, because very quickly you’ll be dreaming of a larger model, then maybe some off-site storage and perhaps even your own cellar. Some here have many thousands of bottles. By always limiting the available space, you’ll avoid the worst excesses of the buying addiction.
Thus I’d suggest just aiming for ~ 20-30 wines to start off with that are wines that really need cellaring. Other wines will appeal in time, so give yourself a little ‘wiggle room’ to accommodate them. Perhaps buy 4-5 bottles of each, allowing yourself to open one of each young (which can be informative when seeing how they age and trying to remember how it was when young).
Keep an eye out for mature/semi-mature bottles, perhaps just in single bottle quantities. These might spark additional diversification, but most importantly they’ll stop you drinking the original wines too soon.
Giscours cellars well, so as you’ve tasted and enjoyed, I’d have that one inked in.
All are very respectable wines, with a long track record. As you’ve picked out the Giscours and the Clape Cornas, then the other wines listed are sensible ‘variants on a theme’.
The key thing to aim for though is wines that you think you’ll like, because Galloni or Parker (or me or anyone else here) don’t have your palate. A lot of people head straight for Bordeaux because it’s a very classic hunting ground for cellaring wine. However you might find you prefer Chianti, or Meritage blends, or Rioja or Douro reds. Hence the caution about filling the fridge up too quickly with what you might feel you should do. Better to fill it with what you do like. For me it was always important to have some variety, because most of our wine is drunk with food, I like having different options that may appeal more/less for a particular dish. On the flip side, it’s good to get a feel for a small number of wine regions, to start to get your bearings. For me there have always been regions that are a key focus, others of peripheral interest, others I’ll try to odd bottle to see if it sparks an interest, and others I’m not yet bothering with, or where I’ve not had much luck so don’t pursue it.

p.s. there is another thread going at the moment covering cheaper cellaring wines. There can be genuine joy in such wines, and the lucky bottles can punch well above their relative status - we remember very clearly a 1997 Dao that we bought from an ITB friend for £3 a bottle and was wonderful at just over a decade old. If only we’d taken more than just the half dozen. Find a few cheap cellaring gems and that might free budget up for something you really fancy that’s $100-200 a bottle.
