Primes for 5D

I probably wouldn't have posted this if the DPreview search function was working.
I'm a Nikon/Fuji DSLR user thinking of dipping my toe in the FF 5D sea.

I'm not that familiar with Canon lenses and am looking for observations and advice on primes in the 20mm to 200mm range. I shoot mostly landscapes, travel and portraits, all available light.
20mm, 24mm, 35mm, 50mm, and 100mm are of particular interest.
