Practically any ten to twenty year old dslr or mirrorless with a half decent lens will give up far better results. Modern cameras will take quality difference further up a notch.

No, phones are terrible for documents. Lens speed is irrelevant. You make a copy stand with good even lighting and "shutter speed" is irrelevant too, within limits with a decent copy stand (for phone or camera).
I agree if you have a copy stand and proper lighting and any DSLR better than 16 M pix, you can get as good as the basic Czur.
BUT:
They can be used "raw".
The high end ones have laser and associated page flattening SW (may not work on Linux, basic capture does work on Linux) and thus are better than a DSLR.
Compared to a flatbed like an old SCSI scanner 20+ years old, or a custom copy stand with lights (for phone or camera) the basic ones are poor. A flatbed that does more than A4/Letter/Foolscap/Legal is very very expensive and unless you have a big ADF and crop spiine off, the overhead photo (Czur, phone, camera) is better. Some non-DSLRs and most so-called "mirror-less" cameras are OK.
Lighting is very important.
