I have an oak reducer molding that goes against my kitchen tile floor

were some small gaps between the tile and molding, anotherwords the
tiles are not lined up perfectly straight. Only like an 1/8" max in
some spots. what is the bets way to fill this gap? I thought caulk,
grout, or thinset. I'm not sure about caulk since it would get dirty.
Any ideas?

There are acrylic latex caulks that go for 2-3$ a tube and dry almost
clear. They make a nice clean looking job of spots like this.
