Present Perfect vs. Present Perfect Continuous
Present perfect simple often emphasizes a completed result or achievement, while present perfect continuous often emphasizes an activity, its duration, or continuation up to the present. The contrast is not absolute: some situations permit both, and many state or single-point verbs are poor fits for the continuous form.
Use present perfect simple when the result or completion is central; use present perfect continuous when the activity or duration is central. Some contexts allow either, and some verbs resist continuous forms.

Further guidance
Completion Vs Activity
Cambridge contrasts the simple form’s frequent focus on completion/result with the continuous form’s focus on ongoing activity or duration.
Verb Boundary
Some state, mental-process, sense, and single-point completion verbs do not normally take the continuous form in these uses.
