Hello, I know that there are many topics on the forum about this matter, but I still don't understand which one I should choose and which hash policy. My configuration is based on a router and a switch and the switch ports will be connected to:
WAN
accesspoint
one PC
Of course, wan and the rest in other vlans. For example, I would like this computer to be able to download at a speed of 1Gb/s. This means that the WAN -> router route has a throughput of 1Gb/s
router -> PC also had 1Gb/s

Why have the WAN going to the switch?

I think 802.3ad mode and layer-2-and-3 hash policy would work fine.
