While I prefer AMS, I think CDG will be fine. I'd generally recommend 2+ hours to make a connection there, but if 1 hr 50 min is the only option, then that's all there is. I would still look at alternates (even if they involve an overnight) just to have as a backup in case things go sideways.

I found signage at CDG to be adequate enough. The only issue I've ever had there was actually finding whatever exit door / platform the Uber pickup area was. The signage that I followed took me to an obviously incorrect area. This was a year ago so might've changed.
