The short answer is every course.
Not sure I quite follow the thread, but the courses that I wish I were a better player are mostly modern courses where a retee is possible on most every swing.
Generally I'm going to avoid seeking out such for fun, but sometimes a big event is held somewhere that you just hate the venue.
Metedeconk comes to mind, where I simply couldn't function on the long claustrophic course in a MET Open and missed the cut by 16 shots.
TPC Sawgrass is a course I simply couldn't function on when I played it(for fun
.
The Kings course at Gleneagles was a course that I happened to like, but... I wish I had been a bit longer(or younger) or straighter as 4-5 of the new purpose built tees for the event made the (now)260-270 carries on those holes impossible for me and I just wasn't striking it well enough to hit the super tight narrow layup areas that were called for on the ultra firm ground to avoid running into the deep, deep cross hazards the bombers were simply flying with impunity to much larger landing areas.
It was interesting to note that on the weekend, the 1/4 of the field that could carry those hazards on Thursday/Friday complained bitterly when the wind picked up that they had to lay up on those holes and then hit a long iron in. Welcome to our world.
By contrast, the qualifying course I played on I was able to use the super firm fairways to great advantage due to no forced carries and multiple doglegs where a curving shot could not only fuel the imagination, but substantially shorten the hole.
