The marketplace and subscription platform is a very interesting area, as it can be very sophisticated, but at the same time, we can also have a simpler version.
I am planning to offer users a marketplace connected to the Zapit wallet with Lnbits as the backend. With this, creators will have their proper dashboard for managing products and a good showcase webpage,
while buyers can make payments with their address, email, or public key.
Here is an example: https://pay.zapit.live/market/stalls/HJASfmLpxmFEV8vZ2pQGQC
