I would venture to say for you it will make little difference. Remember that ultra competitive cycling is a crazy world, where 5 or 10 watts is a lot - or at least enough to determine 1st and 2nd place.
Conventional wisdom is that light is better for climbing, deep/aero for speed - but as always I am sure there are all sorts of exceptions for various conditions, such as a strong side wind.
So I would split the difference. Aluminum semi deep rims, which will still be somewhat "light" although possibly not as light as wheels that cost more than my truck did new.
Then enjoy! As long as you are happy it matters not that Bike Forums says
