If I wanted to go back to film, I would choose 120 mm because of the finer detail you can capture, but you are correct, digital start to finish is easier.
The guy that taught me used a large format bellows style camera which was really cool.
en.wikipedia.org
Bellows allow movements that can be used to correct distortion in a photograph and to avoid converging or diverging verticals. Use of a bellows-based camera can ensure that parallel elements in a scene remain parallel in the final photograph.
In some cameras, the photographer can change the angle of the film plate with respect to the optical axis of the lens, providing alterations of perspective distortion and of the object plane of focus. Bellows may be part of a camera or come as an optional accessory.
