Thanks, finally someone has answered my original question.

Since I do not yet know how FTTH will be configured, I ask, why would such a Brocade or Microtik switch not be able to handle the routing?
And currently I have a Xiaomi Mi 3G (the original, V2 is horrible, and with a different chipset) running PandoraBox (will be running OpenWrt proper when I'll have the time), for routing (I also have a Netgear DM200 running OpenWrt and a newer modem firmware for vectoring, however that is for xDSL (VDSL2 here)), however I am currently trying to get either a Linksys Wrt32X or (preferably) the Wrt3200ACM, 2nd hand, so routing shouldn't be a problem.
You're using these devices for NAT, I assume as all of your internal devices won't be internet-accessible at least on IPv4. So you don't just need routing, right?

Anyway, once you have a switch (media converter, or otherwise) that accepts the SFP, you can VLAN the WAN connection and handle the v4 NAT with a separate device, and it doesn't need an SFP port, just VLAN support. Or you could just set up access ports on the switch and connect 2 cables to the NAT/firewall to the WAN and LAN ports, respectively.

the PoE version of the fcx is one of the loudest pieces of equipment I've ever heard and that's the model you found ( FCX648S-HPOE ) - fans are not moddable. the non-poe version is quiet
Yup, it sounds like a leaf blower in my server cabinet.

Someone smart than me (on this) may already responded - I never tried to feed fiber into Brocade switch, VLAN play out to routing device and back, type of design.

Instead, I am looking at this pretty simple - there are few core functions that network need , 'router' (translate IPs), 'firewall' (apply filtering rules and block ports), switch (convert hardware MACs <-> IPs). These functions could be played by single device, multiple devices, redundant devices, etc. i.e. 'router'+ 'firewall' could be single device or multiple devices , you can get 'all in one do nothing well' device which is ok for typical consumer , etc).

my recommendation is that before you buy anything you take out a piece of paper and draw how you want your network to work. who is landing external connection(s) , who is routing, where is internal IP assignment (DHCP) coming from , if where firewall and if yes who is acting as such, etc. then patch hardware to needs..

my personal current implementation is
WAN ->mikrotik hex3 (router/firewall) -> brocade 6450-24 (switch) -> win 2016 domain controller (DHCP + HyperV host)
HyperV
-> Unifi controller VM (debian no gui install )
-> PiHole DNS filtering (domain controller relays to PiHole which applies the filtering rules).

if something fails or no longer meets capability/capacity demands, I swap that specific device. If I get fiber to the house (which is not available in my area) and little mikrotik device would not handle it I would simply upgrade it . in terms of ports hex S would take SFP 1GB in, RB4011 would handle SFP+ .
