I can't recall if Bakerloo - Central is an easy interchange at
Oxford Circus, though IIRC it isn't cross-platform. This would
probably be my second choice.

It's not. It is down a flight of stairs and down another.

The Bakerloo Northbound and Victoria Northbound are cross platform.
And likewise southbound
