The 2-644489-2: The gold-plated mating surface (30.0µin) is rated for repeated connect/disconnect cycles, so it handles field-service access without the contact fretting you'd see with tin.
The through-hole, right-angle mounting means the pins solder into the board and the wire exits perpendicular to the PCB. The contact length on the post side is 0.130" (3.30mm), which is the standard length for a 1.6mm-thick board.
Yes, this part is ROHS3 Compliant per the manufacturer's listing.
