Finishing a pine staircase - stain/varnish or oil?

[boxster9]

We have had a new pine staircase fitted in an annexe. Looking to have it finished in an oak colour, not too shiny though. There seems to be a number of options available, oil/wax/varnish/stains.

What do we all recommend?

Thanks

Thanks all for the helpful advice.

I have ordered a few of the Osmo testers in a few different shades.

Will trial this on some pine before deciding. We will be carpeting the main stairs, so this is mainly for the spindles/rails and skirting.
