My daughter want to fence off the end of her driveway where it connects to the patio . Not sure what to use to get a strong base for a 4×4

Might be strongest and easiest connection is post in ground. Options there vary.
If you don't mind the hardware showing you can use a connector designed to bolt a 4x4 to a poured concrete footing or pier. But since you are dealing with hardened concrete you will have to drill a hole and use an anchor bolt, or epoxy in a regular galvanized bolt. If you don't own a hammer drill and carbide masonry bits you can rent them. Anytime you're dealing with a concrete slab count on a slow noisy operation.
If the driveway is concrete you have the same problem, but if it's asphalt you could cut a square a bit larger than your 4x4 and use a post hole digger to excavate a hole to sink the 4x4 into.
Thanks , I’m planning on using the Simpson above ground connector and was hoping for feedback on how well they work.
I really don’t want to break up the slab
Privacy fence?
To let more wind/air to pass (alternating bds) vs a stockade fence with no alternating bds On the rails.
I'm not sure how many posts you plan to use, spacing, and so on, but the Simpson connectors are standard for deck building so they should be solid enough for a fence. If the fence has any turns that might cause a concentrated force you could consider working a diagonal brace into the fence itself.
Use metal posts with bolt down bases. These are easily had at HD. Wrap it in wood if you want that look. The metal is thin enough to attach wood or hardware with TEC screws. Drill the concrete for anchors and bolt the post.
