Not sure what you mean by the material available. Are you saying the material available that you’ll be able to print?
If so, I can expand on this a bit. You can print PLA, PETG, and TPU absolutely flawlessly on the p1p. Far better than I was ever able to do on any of my previous printers. And unless you are going to be making parts that are going to see exposure to a lot of heat or pressure, that really should cover most of your bases.
To print stuff like ABS, ASA, or PC you’ll really want an enclosure, and that goes for just about any 3D printer you get. If you do go the route of the p1p, you can actually print yourself an enclosure for fairly cheap. Look up arc or vision enclosures. That being said though, the enclose kit to convert your p1p to a p1s is only $150 which is very competitive with any self made closure when you factor in acrylic costs.
So, my recommendation, if you think you don’t really need ABS or ASA, buy the p1p. It will work great for you. If you decide down the road you want to enclose it, buy the kit directly from bambulabs or print one yourself.
