Can you download stuff from the market if you cancel your sub?

Yes. Anyone who has ever had a subscription will be able to use Marketplace, even if the subscription has since expired.

But keep in mind that as new versions of UE4 become available with new features, some new content that is added to Marketplace may require the latest version. A system is coming to track which Marketplace items are compatible with which engine versions, to sort it all out.

Curious if you’ll still be able to access the market without a subscription. Haven’t read anything about that.

Thank you sir. I am honored to have you answer my question.
