Any, if it has a light hood? The baseline for flatbeds seems to be A4 so 5x4 isn't a problem. The downside is resolution for smaller format originals, in which case a dedicated film scanner is far better. Nikon did a whole sequence of those which remain prized though no longer produced, but can be got secondhand. The earlier ones used outdated computer interfaces such as scsi or firewire, but the later ones used usb & can easily be got to work complete with the well-featured original software, certainly on Windows (8, 10, 11 etc). No 5x4, though - just 35mm or mf, depending on model.
But scanning remains time-swallowing. How much have you got?
Another aspect is that lab scans (I can only assume), tend to be automated & thus lack quality control. I only tried it once (at Ag, with a mf colour neg film), and it didn't cut the mustard - highlights were lost in the scans, but (remember that it was neg film) with a lightbox & loupe I could see detail in the dark areas of the neg.
As with many things, how much fudge can you accept, and how much do you want a result?
I'm not speaking as a control freak - I enjoy many images that people have done using pinholes, reversed element lenses, etc that are intentionally fuzzy.
Find your own path ... dabbling with equipment, technique or aesthetics is less than a quarter of it to my mind. Just seek to convey meaning. Of what sort & to whom are the other great variables ...
