Best Way/Strategy to Mint Art NFTs for Aspiring Artists

Hey guys, we have talented artists in our team and were thinking of leveraging off the social clout of our luxury brand and minting different kind of art related NFTs, including crypto-related, horology related, and more general art related.

Is there a particular NFT platform we should focus on for aspiring artists why are not yet famous or well-known?

Also, is it a generally a better idea once physical artwork is concerned to turn it into a digital format and destroy the physical work or bundle the NFT and the physical work together?

We've been investing in crypto for the last 4-5 years, but are not experts in the NFT space, so I apologize for the newbie questions.
