RB260 and RBFTC stop forwarding traffic if there is at least one 100Mbit-only device connected when at the same time a 1000BASE-LX SFP is plugged in.
Is that an intended behavior? Which Mikrotik devices support 1000Mbit fiber and 100Mbit copper at the same time?

Not my experience, RB260 with 1Gbit SFP and devices on 100 Mbit should work.
Of course you must not feed >100 Mbps data intended for a 100 Mbps device into the SFP and then still expect the other connected devices to work flawlessly.
Some flow control on a higher level (e.g. TCP with suitable window) is always required in switches with different portspeeds. Ethernet flow control usually does not work.
