i'm in the green camp the 2022 SW evergreen fog is perfect, Id'd do trim and cabinets in the accents shown on this site avoid white and grey with your wood floors which are loevely keep it warm! https://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW9130-evergreen-fog
Personally I would prime and paint paneled walls rather than try to fill in the grooves, I'd try and keep them as accents if possible by using bolder colors, like the deeper shade than evergreen or the lighter shades.
