35mm film and 120 film are a similar cost per roll, but with 35mm you get 36 exposures vs 8-16 exposures on 120 film (6x12 and 6x4, with square 6x6 in the middle at 12 exposures). And if you shoot half-frame, the cost/shot really goes in the 35mm direction.
That said, I have a handful of of 35mm cameras (all fixed lens vintage rangefinder) and a post-war Zeiss Super Ikonta IV (6x6 120 format). The Olympus 35DC is my favorite of the bunch - it's automatic except focus - really sharp and fast lens - just a pleasure to use. And a Polaroid Go 2 because it's just dumb fun (way overpriced for the quality, and sensible people buy Instax cameras instead, but the Polaroid form-factor was just too much for me to pass up).
I shoot film because it makes me slow down and think a bit. With my mirrorless cameras, I'm too prone to spray and pray and sorting through hundreds of shots can kill the fun for me. That, and the film look is nostalgic for me - sometimes I just want rough snapshots - feels more like a memory vs the crystal clear high res digital output.

100%, because of the higher cost per shot compared to digital. The higher still cost per shot of medium/large format enhances that effect.
The look and the process explains film over digital.
