For me the issue would be that they mandate the user traffic to be vlan tagged but their modem only exports 1000BASE-T so it's physically impossible for me to get the full gigabit of Internet they sold me.

They most probably sold you 'up to 1 Gb' bandwidth, not just '1 Gb'. Overhead is about the same in these cases. Your losses are negligible. It's more painful having 4-5 (on worst time periods/peers) or 6-7 (on best) of the 'up to 10 Gb' (clearly sold as such) fiber access I have.
