Ask around or rent the SDS hammer drill for quick easy work of it. If you need a channel can use an angle grinder with a masonry blade. Use a small pressure sprayer of some sort with water to keep dust down. Use a shopvac and assistant too for the dust. Then with a couple 1" or water deep cuts horizontal use a chisel bit in the hammer drill to chip it out.

You can also use a regular circular saw with masonry blade for horizontal cuts. I've fount it easier to cut say 1" deep to get your quick line and make it straight to start then cut full depth as needed and blade will follow first cut. Again light water spray helps. Concrete patch can fill it then a little paint an nobody will ever know.

On inside use angle grinder to cut rectangle for a box at the location. Then chip out, a 3/4" concrete chisel can do detailed work.

Or run conduit on outside. The exterior grey pvc can be scuffed and painted to match exterior.

There's also lots of different trim options with a groove in back or hollow to run cables.I always suggest 3 cables to every normal location with 5 or so at a tv/media location.

One may be able to run through ceiling/attic area or a basement.

There's lot's of info here and in pinned comments.
