If you do a regular speed test on a laptop is there also a similar slowdown? Or is it only the Foxtel box? When the cable modem is plugged into the mik is it put in bridge mode or are you double NAT’ing. Nothing really jumped out at me in your config. I guess you’ve tried with and without the simple queue.
every other device on the network performs normally, it’s just foxtel acting up.

the modem is in bridge mode, the telstra firmware is not that good and is too dumbed down, bridge mode is the best option.
I also tried with bridge mode off, NAT switched on, on the modem, unfortunately no change.
I guess the next thing I’d try in this situation is put a managed switch in between the modem and the routers and mirror the traffic to wireshark to look for any differences when it’s working vs when it’s not. Don’t know if your comfortable at that low a level.
Don’t know if you have access a smart/managed switch or not, I’m not sure if the switch chip in your 951 could be used to mirror or not (might only be in the newer CRS devices) and I’d prefer switch hardware mirroring rather than a bridge+mangle sniff rules as you want to avoid the mikrotik cpu and any possible impact that might have on your bandwidth.
You’d be looking for differences in the packets that could be nailed down to the different setups. Eg qos values, MSS, packet size etc. maybe even do the same with that netgear router that worked to see what it might be doing that the 951 isn’t. Otherwise I suppose we would just be running through a laundry list of guesses, which you look to already have done a lot of.
Sorry I’m going away on holiday so won’t be here for a while.
But basically you want to setup a switch group on the CRS for a few ports between your cable modem and the various downstream routers (maybe another one to plug the Foxtel box in and look at that traffic).
Then setup mirroring to send that traffic to another port/host running wireshark to look for any differences when it’s slow vs fast.
You want to do mirroring as its wire speed in the switchchip and you don’t want the CRS router CPU to get in the way (like it might be in the 951) so no bridging and sniffing via mangle rules.
Oh and no you should only need the one CRS and yes you would only want a minimal config (enough to get management access via winbox - lots of wiki/forum threads about that)
