Those are not oak cabinets. As I started reading this thread, I was starting to compose a reply -- "Am I the only one thinking those are not oak?" but then started running into a growing number of folks saying the same thing. They have a tight grain that looks like maple or possibly cherry, but the way they appear to have taken a stain makes me thing maple. Maple has a tendency to not accept stain evenly and you have some lighter and darker areas. I suspect they are not alder because that is a softer wood and I don't see any dings. They do appear to be in good shape. I'd work with them. As said above, if you have money for granite and tile floors, you have money for paint or stain. If you are willing to take the time to learn and DIY on the cabinets, you may be able to do both. You showed us a lot of the kitchen, but not two things I'd like to see -- your lighting and the cooktop. Do you have a vent hood? Does it exhaust or recirculate the air? I'm wondering if the cabinets have years of gunk built up on them. They look not only yellowed, but possibly dirty or dry. I would give them a really good cleaning for starters. You can't paint or stain until you do that anyway. Then I'd look at the lighting -- It looks like it may be adding to the yellow cast to everything. Any chance you have an older florescent fixture in the kitchen? The wood color looks better in the breakfast nook than it does in the kitchen. Changing or improving your lighting and cleaning your cabinets could make things look a lot different and neither of those should be budget busters. I would paint the walls with some color and then step back and take a look. If you want darker hardware, I'd buy new. It doesn't have to be expensive, but painting hardware is likely to be very temporary. So far, with DIY, we're looking at a few hundred dollars. I would like to remove the soffit in the kitchen itself if possible. If not, I'd paint it or give it a deep crown treatment to carry the cabinet line to the ceiling. You could also paint the ceiling crown to match the ceiling if it will not bother you that is will then be different that the rest of the house. I would not paint the window trim -- the window itself is stained wood and matches all your other windows. Once you get to that point, I would make a decision on painting, gel staining or stipping the cabinets and refinishing. Those are all things you can DIY, but paint and stripping will be time intensive -- which is why there is a lot of cost to them, especially if they need a lot of cleaning and prep work. You don't want any painter who isn't looking at good prep work because the job will not be good or last unless they do it right.

I like the 12 x 24 tile in the first photo as your flooring (could maybe be slightly darker). I think what your missing in this bathroom is warmth, so I would introduce a wood grain on your vanity, scratch the granite looking Greenstone counter top and go for an all white counter in Greenstone or a slab of marble (you could probably find a remnant for the size of your counter) to bring in some warmth. I'd lose the tile accent (IMO tile accent strips are dated) and go with a plain white subway tile or Carrara for the bath and the shower (on the larger size - 6 x 12 is a nice contrast to 12 x 24 flooring tile - usually its a 12 x 12 cut in half and most masons will do this no problem). Nice size bathroom - good luck :)

If it's within your budget, one idea could be to add a built-in banquette where you have the bench currently. I would run it along the back wall with the window (from about where the window ends) and along the bench wall. This would give you a bit more seating, and then perhaps your table could run a bit longer. I really like the paint color as is, but nice bright white to match the wainscoting could feel really fresh as well. Do you have any collections of kitchen-like things? Maybe glass bottles, or old kitchen scales....it could be really cool to have some shelves on the wall between the window and the corner and showcase any sort of collection you may have. For the larger wall you could do a photo gallery wall. If you stay with the same paint color, I would go with white frames. If you lighten the wall color, black could be nice to tie in with the fireplace. I'll attach some photos for ideas. Good luck!

If the goal it just to make the cabinets look better for showing a home, products like Old English are fine- new owners are likely to replace cabinets or refinish. I also have had luck with pure nut oil (in the cooking aisle). Almond for lighter wood, walnut for darker or a combo for medium color. I remember years ago, the fix for a scratch on wood was to cut a nut piece, like walnut or pecan and rub it over the scratch. The oil in the nuts has something in it that stains the raw wood. If you can find unrefined oil, that would be better. I see some almond oil products on amazon for refreshing wood.
