After having the same trouble with Minecraft - Nintendo Switch Edition, I managed to recover all downloable content previously purchased on Marketplace with my Microsoft account. Try this:
1) Log in with your MS Account (Outlook, Hotmail, etc) in the XBox Live website (on your PC). Use the same MS account you registered in Minecraft to purchase DLC in the Marketplace.
2) Select "account preferences". Update your player tag (the name displayed for the community, usually printed on the left/botton corner of the main menu of Minecraft). Once your player tag is updated, keep your session started on the PC.
3) Turn on your Nintendo Switch and make sure your Internet connection is working. Open "Minecraft for Nintendo Switch". Be patient . Your new player tag should be displayed in less than 30 seconds. Marketplace will be downloading the content you purchased with that MS content before.
