Cheaper flatbed scanners will give you a couple megapixels from 35mm color negatives, proportionally more from MF negatives. They will struggle with slides and B&W negatives due to insufficient density range, you'll get blown highlights and/or crushed shadows on high contrast shots.
High-end flatbed scanners like V750 are generally fine for anything, unless you have particularly high contrast B&W film or want maximum quality, down to the grain scans. But they're quite pricey.
Dedicated 35mm film scanners will pull maximum detail from anything short of exotic technical film, but they're similarly pricey, and rare to boot. Dedicated scanners with MF capability are probably way out of your price range.
Avoid cheap "film scanners" that are just a cellphone sensor and some shitty backlight in a box.
If you have a macro lens, your digital camera can make a better scanner for 35mm film than any flatbed, but it's gonna require some jury-rigging.
Note that progress in film scanner technology stopped in the early 2000s and basically everyone except Plustek and Epson dropped out of the market; a 15-year-old scanner will scan just as well as a brand new one, if you can make it work with a modern PC.
