> Sia records the data on chain where as filecoin opens up a market for storage and retrieval
I think what you're trying to say is that with Sia, you are responsible for choosing which hosts store your data, whereas with Filecoin, you submit an open contract to the network, and any host that satisfies your terms can claim it. Both platforms have a market, but Sia's is off-chain and Filecoin's is on-chain.
(Also, to be clear, Sia doesn't store actual file data on the blockchain itself -- it's been clear since the early days of Bitcoin that storing large amounts of data on-chain isn't viable.)
> Sia requires you to run a full node to interact with the chain and data
Technically it's always been possible to store and retrieve data without running a full node (you just need a few secret keys, hashes, and IP addresses), but I'll grant that it hasn't been very user-friendly until recently.

Can you be more specific?
