With a FF, 85mm-135mm is a classic portrait length, 35mm is a bit too wide. If you do not have room to stand back, find out which focal lengths you can use by using a zoom and noting the best focal lengths.
My 135mm L is my favorite, but, I am back quite a long way typically. I also use a 85mm f/1.8, but it gets frustrating when it picks up a reflection and shows a ton of purple fringing. If I used that focal length more, I'd go for the f/1.2.
