Someone told me not to wax it, as would likely mark any timber in contact with it.
:?: You don't have to worry about that, thousands of workbenches have been waxed without it causing a problem. If there were an issue with this we couldn't wax the soles of our planes to make them slide better.

I would like it to look as nice as possible and also to be protected.
If you want to provide more protection than wax alone would provide you have a choice between a film finish (shellac or varnish) or penetrating finish (an oil or 'oil finish' such as Danish oil).
These days film finishes for workbenches have many detractors but you'd join a long line of woodworkers if you chose to use one. It's actually not uncommon advice to shellac and then wax on top of it, to further help the surface shrug off glue spills and what not.
