Put a wood board on home wall concrete
1) To find wires buried near the surface in walls you can use a "cable detector" They have various names. One example is the Bosch PMD-7.

2) The type of screw depends partly on weight. For concrete, you could use a goodly number of tapcon screws or perhaps a fewer number of sleeve anchors. Check the weight rating of the screw and work out the expected load of your wooden panel plus all the things you will hang on it.
