So....... steering wheels versus the interior;
Some wheels look better against a darker (or lighter) background. Also, a “classic” looking wheel, like a white banjo or white classic tensioner might not look as good against a more modern (sculpted) interior, whereas against a classic interior (read that simple, flat) it might look better.
Wooden steering wheels (Nardi, MOMO, even some classier Grants) look good with almost any interior color, so then the lightness of the wood grain, the spoke shape and configuration comes into play and, again, the final look is up to you.
Lastly, you may like the look of a leather-wrapped wheel. We don’t see many of those (the two or three I’ve seen have been black) but in the right interior they can look special.
Sometimes you “luck out”. My car, originally, was black gel coat and I chose a deep Burgundy red interior similar to a Pontiac Wildcat from the 1960’s that an uncle had. It looked really rich. But then I decided to go with a pearl white exterior and kept the burgundy interior because my Mom had a 1966 Ford Galaxie 500 XL with the same color combo and it pops.
My car is a widebody (mild fender flares) - it is more of a 356 hot rod than a classic, so I can get away with some ideas that are out there a bit, like a rosewood Nardi-like steering wheel, burgundy interior, Celtic Knot horn button (we’re both Irish), nerf bars instead of bumpers and a few other things, but all that adds up to my individual taste.
Have fun with yours!
