I have more scanners than space.
The scanner that I use for LF and ULF negatives is a Scitex Creo Eversmart Pro. Big, very heavy (165 lbs), but about the best flatbed scanner ever made. Cost about $30,000 ten years ago and can scan up to 12X17" at 3175 ppi anywhere on the bed, or all over the bed. Stated optical resolution is very close to actual since I test it at over 60 lp/mm.
For MF I use an even older scanner, a Leafscan 45, made in 1997. I scan MF negatives with the Leaf in two passes at 5080 spi, and then stitch the files together. Sharpness is better than most drum scanners as real resolution when scanning at 5080 spi is over 4500 spi. The Leaf 45 is also fairly large and heavy (about 80 lbs).
I also have an Epson V700 which is used primarily for proofing. However, the model I have is quite good, delivering a maximum of about 2300 spi in real resolution. For LF film it would give great results up to about 3X, which would give a 16X20" print from a 4X5 negative, or a 20X28" print from 5X7. You could print larger with good processing. You will get best results using the super high resolution lens, and you must test and use a film holder that will place the negative to be scanned at the plane of best focus. I recommend the Betterscanning holder for the V700, which allows for even better scans with fluid mounting. The V700 would also be good enough for MF negatives for print size up to about 4X.
