Important to know is that USB4 in alternate mode can now do DisplayPort 2.0 which is up to 80Gbit/s. Whereas Thunderbolt 4 itself only does 40Gbit/s. So my recommendation is using one dock for charging, Ethernet, USB. Then using a second cable in DP 2.0 mode for your monitor(s). The only problem is that with charging it can make docks also quite flakey.
