Oh yes.
The front row (which will become the only row) is noisy because of the galley. In a few AF flights several FAs chatted noisily while having some food for part of the night.
For the same reason, I avoid CX front row in F.

Also a lot of foot traffic (FA going to the front).
Sometimes a couple (or two colleagues) sitting in middle seats can conduct noisy conversation, especially when they have their earphones on.
That's where CX suites are great.

IMO no suites are closed-roof. But it helps to have a fixed shell around the upper-body part.
