I haven't tried those Silicom cards but I have a couple of 6-port
HotLava 1000base-T em(4) cards which are working nicely.
I don't see I340AM4 on the list in the em(4) manual. I can't say whether
this is just an omission from the manual, or whether it's unsupported.
82580EB is listed there.

When I had a circuit delivered on single-mode fibre I couldn't find
a suitable 1Gb SFP card for any sensible money so I used a 10Gb card
instead (in my case some 82599-based Intel SFP+ which uses the ix(4)
driver), which also work with 1Gb SFPs.
$ ifconfig ix1 | grep -e ^ix -e media
ix1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
media: Ethernet autoselect (1000baseLX full-duplex,rxpause,txpause)
$ dmesg | grep ^ix1 | tail -1
ix1 at pci1 dev 0 function 1 "Intel 82599" rev 0x01: msi, address
00:1b:21:c0:25:bd
