have a look at ubiquiti routers: their edge router lite is capable of handling gbit, and can protect against buffer bloat at up to 100mbits/sec. the only doznside is that they are harder to manage than the average consumer router
The edgerouter lite is quite old at this point and if the purpose is to use QoS to manage buffer bloat then the EdgeRouter X which is only like $50 would be faster. The edgerouter lite is of limited use for new installations nowadays.
Edit2: Arrgh, and didn't read far enough on the thread before sticking my foot in it where you otherwise discuss the Mikrotiks.

Going up to the question of Slovenia higher in the thread, there's a Slovenian vendor who has the "hAP ac" (dual band, gigabit, SFP, USB port) for 121 Euro (https://www.virtua-it.si/izdelek/mikrotik-routerboard-hap-ac...) along with other less-capable and cheaper models.
They cost about $100
