Oh, the ath10k used to suck! :/ https://forum.openwrt.org/t/aql-and-the-ath10k-is-lovely/590...

A sore point for me, is that yes you do need FQ+AQM on your fiber link, and if you are running linux - you probably already are running the no-fuss-no-muss BQL + fq_codel combination on that uplink at that line rate. No knobs, it just works. These days you might want to try cake with no bandwidth setting as a default instead, there. No explicit shaping required, just the native backpressure from BQL.

It is unfortunately highly likely that your ISP is using something like a policer or tail drop on your downlink instead of preseem or libreqos, so believe it or not, shaping the downlink can help a bit more, in some cases. I am a big believer in actual measurements using the flent tool: https://blog.cerowrt.org

I find it weird that mt76/mt79 pcie or m2 cards are so rare. I would like it if they penetrated the laptop market where intel presently dominates with that.

Cynically the "best" AP may often not be the actual one you want. Too many best algorithms depend just on RSSI rather than (for example) sporadic interference on the same channel, causing jitter. A narrower channel width with less folk on it is sometimes better than a wide one duking it out with everyone else.
