That switch is total overkill. But with the provider you're with the only real option is to basically have a flat network or Double NAT because of how they've configured the ONT to be the gateway. They're more consumer based. The switch itself isn't really a router.
If you went with a provider like Quic (not an endorsement, but they seem pretty good) and use a router that can do 2Gbit you've got a whole lot more power in what you can do with the traffic coming into your network. There are for example a few routers in the Mikrotik name that are complex, but have a craptonne of power to do some pretty neat things with. Or you can build your own router out of a x86 PC along with PFSense / a few 2.5Gbit NIC's which is a rather cheap way of going too.
There are a number of options to do this cheaply if you're really keen on learning - my pick of the lot would be the PFSense / OPNSense option. This PC for example is rather cheap, tiny but seriously cool:
