I had the same dilemma when I redid my kitchen.. and the advice I was given, "if you are questioning if you will tire of beadboard, chances are you will".. full disclosure, my house was also not a bungalow so in fairness, beadboard would be more appropriate for you. Hard to go wrong with either choice.

As for your other 2 questions -

2) while I have not the joy of living with or cleaning beadboard, it seems to me it has nice dimension without having deep grooves so it would not be too hard to clean.

3) I see it more classic than country.. depends on what you do with the rest of the design.

Good luck and post pics.
