Found some things about the online service.
Same question but kinda different answerAfter my Nintendo Switch Online membership expires, will my online save data and my Nintendo Entertainment System™ – Nintendo Switch Online data be erased?
Save data stored via the Save Data Cloud backup is available for as long as you have an active Nintendo Switch Online membership.
Classic games in the NES – Nintendo Switch Online collection and the save data for those games will not be removed unless the user chooses to do so manually. These items are stored locally on the Nintendo Switch system but cannot be accessed without an active Nintendo Switch Online membership.

Save data stored with Save Data Cloud cannot be kept outside of the duration of your Nintendo Switch Online membership. Nintendo Entertainment System – Nintendo Switch Online also uses the Save Data Cloud, so the same applies. However, if you keep the Nintendo Entertainment System – Nintendo Switch Online save data saved locally on your Nintendo Switch console, then you can use it again if you purchase another membership.
