Which one is usually used?

CNFT.IO is the mainly used one, creating custom NFT contracts have not been widely introduced in Cardano Blockchain, however to create NFT collection you can make Policy ID stable and create a collection.
To add a collection and get verified on CNFT.io you will need to add ur policy id to their github and request a pull

It is pretty easy to create NFTs on Cardano but the secondary payments is still not solved exactly yet, some other trusted marketplaces are:
EXNFT io
Tokhun io
CNFT io
NFTmaker io
Nextcnft com (this is not launched as far as I remember)

Good luck and hope u create a nice collection.
