When these Enum classes were added in matplotlib#18544, they were supposed to be for documentation only. To that end, matplotlib#22055 was a followup that ensured that only the strings were exposed from the getter side. However, when user-supplied cap/join style were added in matplotlib#20914, they were only for the Enum type instead of the string, so correctly allow strings here as well. Also, specifically type hint the return values as literals, as was done in matplotlib#25719.
It is not possible for `get_marker` to return another `MarkerStyle`; the `__init__` only takes one to make a full copy of it. And `get_alt_path` is only available for e.g., half-filled markers, but not all.
