I'm thinking of a wall fixing only, as I have a new wooden floor. But, my wall has a skirting board which means the back of the safe would not be snug to wall - there would be a 1.8cm-1.9cm gap. Is that a concern?

I would recommend removing part of the skirting board and having the safe bolted flush to the wall, as any gaps could compromise security.
