Nice choice and budget to have. How much of that budget do you really want to spend?
Few questions you might want to think about. I’d look at stuff like how much climbing I do, if your typical routes are very hilly you might want lighter wheels and shallower rims as your avg speed will be lower. Lots of down hill and it also worth considering the braking qualities. If your rides are mostly rolling / flat you might trade off some weight for more aero. You might also want to think about your avg ride speeds as deeper rims tend to be less stable at slower speeds.
Will you be racing on them? What sort of racing? You might want to think about how easy they’ll be to service, repair or replace. Wheels like the FFWD that come on standard DT hubs might be a good option if racing.
How concerned are you about aero performance? If you’re spending a lot of cash to buy aero performance then you want to know you’re getting something that works. Can be hard to find good test data on some wheels. Zipp’s are a very common sight on time trial bikes as performance is known to be good and there’s a lot of test data out there (most manufacturers who do publish data will often use Zipps as a baseline comparison.)
FWIW, my race/summer bike has Zipp 404 clinchers (front also gets raced on the TT bike when not using the 808.) Though I do also have some 50mm Planet X tubs that I’ve used for some crits when I’m worried about crash damage.
