The CAD files that @TimWescott referenced contain the PCB layout (in the schematic zip, not necessarily where you would expect it). As typical for ST, they are in Altium.
The footprints look like this:
Outer copper dimensions are 100 mils x 40 mils. So maybe an 0805 would be appropriate.
Of course if you're doing a few by hand all you need is a soldering iron and some solder. Lead-free will work even better than nice 63/37 solder.
(below does not relate to your eval board)
I note that a Nucleo board I happen to have in front of me at the moment (G071RB) has jumper dimensions that are hard metric and a bit smaller (2.4mm x 1mm) and they bridge them with 0603 zero-ohm resistors. Unusually, they mask the pad off partially with solder mask (i.e. the pad is partially solder-mask defined). Probably some compromise to allow the boards to be reliably machine-assembled with zero-ohm 0603 parts- so the asymmetric pads don't pull the resistor to one side when the solder is molten and look bad or maybe even tombstone.
