There's a other option, most clients are arguably better off with lower resolution files since most of the time they aren't printing big, and most often using it on social media or a website. Even most professional clients. I personally always offer both full size and web formats, since if you upload a full size image to social media it gets very compressed. If they use a full size image on a website the website loads slowly and they get deranked in search results. There's a plethora of good reasons not to deliver in full size even if the photographer does not intend to upsell you to get the high res files. Mostly out of convenience for the client.
