Another solution: run ethernet cables outdoors on the ground.

You can do ethernet cables outdoors from your router in your house to your router in your office. Either thin cables that go under doors, or outdoor rated ones, both can work fine.

This same approach can work inside a house as an alternative to mesh networking or running cables through walls. The cables don't have to be invisible (underground or in walls) when you have tough constraints, unless you want them to be.

The direct line across would get run over by cars. Indirect routes would still have to cross pavement and look ugly.

And then there are still those six feet of stone that needs drilling through to get the cable outside and back in.

There is equipment that will dig a small tunnel like thing under concrete, avoiding needing to destroy your driveway (assuming there is space on either side) . Won't be cheap, but it's possible.

Search for "cable protector ramps"

Thin cables designed to run under doors or windowsills are an option. Search for "flat ethernet cable"

It seems like you prefer your setup for good reasons, and these solutions above are both ugly, but I still wanted to note to others reading this that workarounds exist.

Six feet?

How about using fiber optic cables for this? I saw a few videos on YouTube showing the installation for home internet

To what end? The runs aren't going to be long enough for fiber to provide a benefit, and the transceivers are more expensive for consumer use like this.
