Everything else is included - Fast-track security (where available), priority check-in, 1 x 23kg checked bag, lounge access (+ 1 eligible guest) and complimentary seat selection (includes exit rows for oneworld Emerald). Finnair’s IT, at least with regards to status benefits, has been programmed rather robustly and one won’t encounter any issues utilising these benefits. The only downside is that Light tickets are completely inflexible (unless an involuntary change situation comes up of course).
