The higher the better until you see diminishing returns.

1200 dpi scanning 35mm film is effectively less than scanning a 4x6 at 600, if you compare the number of dots per image height (dpi * physical height)

Also, photo labs often perform some basic color/exposure correction automatically during the print process, so expect to need to do that for film. I strongly consider obtaining a color calibration target that matches your film (Google search "Wolf Faust") and profile your scanner.

Also, what model Epson flatbed is it? Some of them have a great rep, some are utter crap. For example, the marketing for the scanner included with the RX595 all-in-one printer/scanner outright lies - it claims 48 bit color but it only does 24 bit color, I've never seen an option for more than 8 bits/channel (24 bpp) in any software, Windows or Linux. For this reason I probably won't be buying any Epson products again - In addition to their Linux support being awful compared to what it used to be (drivers used to be fully open source but now have binary-only components), at least some models in their product range do not perform as specified. I realize the RX595 is low-end, but if it says it does 48 bpp, it should do 48 bpp!
