> No one wants to use 10g ethernet when DACs are cheaper than cat7,
You don't need Cat7 for 10G.
Cat6 is spec compliant up to 55mm. Cat6a to 100m, which is the same as Cat7.
If you're doing short runs like to a nearby switch, good Cat5e works fine in practice. I've run 10G over Cat5e through the walls for medium runs without errors because it's all I had. It works in many cases, but you're out of spec.
I use DAC where I can, but most people just want something they can plug into that RJ45 port in their wall that goes to the room down the hall where they put their switch.
There are several SFP+ to Thunderbolt/USB4 adapters on the market. Not cheap, though.
