Did I do wrong for buying an i9-12900k?

So I just basically almost got yelled at for getting the I9-12900k processor and was told I should have gotten AMD Ryzen 7 9800XD. But I already have my Processor on standby to be built into my PC. So I'm unsure if it's massively flawed or bad or is it really that dire to have not gotten that specific processor and did I screw myself over by getting it.

Update: I finally received the PC so far runs smoothly and the cpu temps have been fine. I do understand peoples concerns future upgrades but I don’t mind dealing with it when the time comes.
