Also a PC Engines APU4 will do the job
(https://inonius.net/results/?userId=17996087f5e8 - this is a
1gbit/1gbit, with Openwrt/sqm-scripts set to 900/900.  ISP is Sony NURO
in Japan). Will follow this thread to know if some interesting device
popup :)

The best answer ATM seems to be a combination of a raspberry pi4B with a decent USB3 gigabit ethernet dongle, a managed switch and any capable (OpenWrt) AP of the user's liking. With 4 arm A72 cores the will traffic shape up to a gigabit as reported by multiple users.
