To go against the grain, I love your kitchen! It's very country cottage.
I can understand you're bored and want a change.
I would: Light worktops if you can afford stone, dark slate effect if not (my in-laws have this and it's lovely)
No tiles, just a splash back (plain or image of your choice)
Match new handles
Paint in a colour to compliment the space
Pick a floor that will tie the whole thing in!
We've not long moved into our new home, and we have a solid wood kitchen that's very dated too (I'll add pic). I'm planning on updating, not replacing.
Years ago, in a rental, I covered the kitchen doors, worktops and tiles in transfer stuff. Looked great for about a year, but by the time I was leaving a few years later it was horrible. And a pain to clean once removed.
