Yes, they also offer CF options in PLA and PETG in their filaments. If you just to go the filament section of their site you will see all of them. Strong is a relative term I suppose, but PETG basic is pretty strong. That's also where getting into how many layers, infill types, etc come into play. I don't pretend to be an expert in all of that, but it should print any filament any other 3d printer prints that isn't specialized in some way.
All I know for sure is they say not to print TPU (flexible filament) through the AMS, but you can print it by simply feeding it into the back of the machine. There are prints out there for a Wye that allows the AMS and an external spool to be used at the same time. Lots of options.
I will say, in this case Youtube is your friend. Tons of information about there on this machine and what people have done with it. Tips, tricks, etc.
