If the viewing distance is great enough, a modest sensor digital camera can work surprisingly well. This is due to the human eye's way of putting structures like dots together to create an image within the brain. There was a time not too long ago when 35mm color slides were commonly projected to far greater than 20x on to a screen with very good visual results. Similar applies to cinema images where cine 35mm is projected to very large sizes with very acceptable image quality. This works due to viewing distance.
IMO, the days of widely available high quality film based color prints is mostly gone due to lack of materials and related. Digital printing has mostly taken over as the principal means to produce a color digital print. Given this reality, why not consider using a medium format digital camera with the appropriate lenses to achieve the large color print as needed?
Moving into a sheet film camera from roll films is not as simple as it appears, there is a significant learning curve involved. It is highly recommended to learn and try using a 4x5 first before diving into a larger sheet film format. Expect to burn and waste a LOT of film with a LOT of camera time before getting far up enough on the learning curve to gain the ability to used this imaging system to it's fullest capability.
8x10 makes GOOD contact prints, even larger sheets of film can produce larger GOOD contact prints. But when it comes to enlarging the 8x10 or larger sheet of film, it become a significant technical and physical challenge due to the sheer size if devices involved. The idea of scanning to produce a large size image data file has it's own set of difficulties that should not be taken for granted.
Camera, optics, film, processing choices for 4x5 is GOOD, for 8x10 these same choices are much less coupled with essentially an imaging system that is often four times the size, weight and more.
The often forgotten format is 5x7 which is pretty much the ideal trade-off between the two if one were to keep the entire image making process film base, not scanned.
Image "sharpness" or resolution alone does not make an emotionally expressive print as the emotionally expressive image is far more complex than simply "sharp".
