Is the standard hydrogen electrode always the anode?

No, it depends on the value for the other electrode in the galvanic cell. The standard hydrogen electrode is always 0. If the standard reduction potential of the other electrode is lower than 0, then that will be the oxidation half-reaction and will be on the anode side of the galvanic cell.

Also remember, when writing the cell diagram to add Pt or any other inert metal.

Depending on the scenario you suggest, when measuring standard cell potential of other substances, then yes SHE is always on the anode side by definition. Otherwise, it can be on either the anode side or the cathode side.
