I’ve gone through three point and shoots (a Nikon S210, a Canon Powershot A630, and a Nikon L830), my parents have had a couple (both Canons), and four of my siblings each had one at one point in time (all Nikons).
Rule of thumb that I’ve found to be true:
Most cheap Canon point and shoots have a manual mode (and possibly even aperture priority and shutter speed priority modes). It’s clunky and hard to use, but all of your settings are there (ISO, shutter speed, aperture).
Most cheap Nikon point and shoots and even the entry level superzooms like the L830 don’t, though there is ISO control, white balance calibration/presets and exposure compensation.
