I would detach one drive from the mirror first and make the raidz1 with the two drives if that’s possible (not sure if it lets you create a pool in a degraded state)
Probably just go with SSD storage because 2T is fairly low for hard drives these days. Still a pretty good idea to do a mirror.
Pretty much any CPU that isn’t a raspberry pi will comfortably max out a gigabit Ethernet connection.
