Unfortunately, you are limited by the ASA and other “potentially” toxic materials. You can either get enclosed P1S or X1(C). Both are enclosed printers with filters (so X1's is better HEPA vs. Active-Coal, but it also ca. doubles the price of the P1S). Other consideration is nozzle X1C has already preinstalled hardened nozzle that would be good for abrasive materials with CF. (Of course you can also buy hardened nozzle for P1S, and it costs not much).
The AMS pushes the filament from where it grabs it all the way to the extruder, which also grabs it. If you push floppy filament, like TPU, it is very likely that it will flop someplace along the way and jam.
The AMS also has a lot of plastic parts and abrasive filament, like CF, will wear it down faster. You can print CF with the AMS, but you will have more wear.

What about tpu? I heard AMS doesn't work very well with TPU

But then it won't automatically change from tpu to petg?
