I do not think that there is a crypto only comprehensive and reputed platform available as of yet and it would take mass adoption in real sense before we would be able to see some platform like that. There was a store that was selling gadgets and other electronics and was accepting crypto like 2 years ago but when i dig further i came to know that it was scam, they will tale payment and orders but will never send you the product and you will not get any response after that.
