Get the multimode SFP from RME, then you have no issues with possibly wrong wave length.
On the HDSPe MADI FX you do not need an SFP, it has the transceiver built-in.
But you need a proper OM4 (or OM3) multimode duplex cable with LC/SC plugs to connect HDSPe MADI FX and M-1620 Pro D.

I wouldn't daisychain if you have enough madi buses. Every additional device in a chain adds 3 samples or latency for the forwarding of samples to the next device in a serial chain.
You can connect the M-32 Pro optical, I would to this on the next free optical bus.
With optical connections you have also galvanic isolation, so why BNC?
Then you would need a 2nd SFP from RME for the M-32 Pro and a 2nd OM4 multimode duplex cable SC/LC.
