I think that your package needs to depend on sf in order for this to work. Specifying it in Imports may be enough to make the plot.sf S3 method available to the user.
Specifying a package in the Imports field of DESCRIPTION guarantees that it will be available to load, but doesn't load it. Importing something from it via the NAMESPACE triggers a load, as does executing code like pkg::fn, or explicitly calling loadNamespace("pkg"), or loading a package that does one of these things.
You may encounter other problems if you go this way, like R CMD check complaining that you don't use the package you're importing. Loading the data from a file on demand would also load the sf namespace and thus solve the problem.
Workarounds for the check complaints are discussed here, among other places: https://stackoverflow.com/a/75384338/2554330 .
