I think painting the cabinets is a huge improvement! Good job! It looks so much "fresher" in there. I would probably paint the file cabinet too (not sure how easy that is to do though). Adding some type of pretty fabric to the window area and on the shelving would be a nice touch. I like the blue and white so I'd go with that (maybe toile). You're hard work in there is really paying off. :)

Painting everything white was definitely the way to go!
The colors you are considering sound good to me. I would suggest picking out the fabric to curtain off the open storage before making the final decision on the paint. Here's how I hid my open cabinets with a curtain in my laundry room

California, Thank you for the compliments! I really think the file cabinet should be painted as well, but hubby isn't on board with the idea. I'll just do it when he's at work! ;)

Daisy, I LOVE your curtains! Your laundry is one of the dozens of pics I looked at before deciding to paint mine! I love your little container in the corner. :)

I was afraid I'd get comments like "Why don't you buy some real cabinets for that room?" I appreciate that everyone here seems to have the same mindset I do...make it work. :)

Okay, so I've decided that I do NOT want to stencil in this room. The stencil paint just doesn't show well against the white. I'll be trying something else.

Anyone have any really good ideas?

I think your ideas are great. Once you paint and get your fabric treatments up it will look entirely different. I would definitely put blue on the walls for some punch. You won't see much of it, so a bolder color would be just fine.
I realize that your wire organizers above the washer and dryer are handy, but would a compartmentalized basket or 3 baskets sitting on the file cabinet work well for you? It would be a pretty storage piece and add to the country feeling you're going for. You could also put a tray style basket on top of the freezer to hold/hide necessities.
Have you thought about burlap for the curtains? What is more country than that! It works your tan into the scheme, is tough, and would look so pretty with an accent fabric sown on the bottom and/or edges. A tan denim would work well, too.
Instead of stencils, you could hang a couple of cute plaques using those Command adhesive things on the door and a cabinet front or two. I know that TJMaxx/Homegoods always has some items in the primitive/country style (not necessarily laundry themed). Here is one in the link below that's kind of cute. I just wouldn't go overboard.

I just love it when someone makes a utilitarian space pretty. I'm a big fan of "use what you have", so I think you are doing a great job!

Here is a link that might be useful: Plaques

I love that plaque! It is so me. :) I also like the idea of burlap or tan denim for the curtains. I hadn't thought of going that direction, but then I could put blue on the walls and it wouldn't be overkill.

Baskets are a good idea, maybe I'll see if I can get some small ones to put in there. I'm not sure where my closest TJ Maxx is, but I need to find one...especially since someone found a tin like Daisy's!
