wife and i remodeled the entire ding dong house but since you're asking about kitchens:
i did the easy installs such as cabinets and appliances. professionals did the countertop and backsplash. i haven't gotten to the crown molding yet... it's only been like 18 months quit asking!
cabinets:
chinese. KZ Cabinets in san jose. there are literally dozens of vendors though, and every area is going to have their own. black wasn't our ideal but there was no chance of custom for us sowe liked the style and black could be made to work. with chinese cabinets, the color and style are in lock step with each vendor. want my style in pink? you'd have to find another vendor or refinish them whcih would likely still be cheaper than custom.
layout: the first cabinet place i tried actually did the layout, even though we didn't get anything from them, and it was free. they all use the same standard cabinet dimensions that are independent of style. there is a "work triangle" in every kitchen. some of them suck, some suck less than others.
quality: i like them better than a friend that had a hookup on custom units. the downside is he has some cool features that aren't available from the chinese cabinet importers. his cabinets have cheapie construction too (part of the hookup price i assume) whereas mine have solid wood drawers that are dovetailed together, his are pin nailed plywood. we both have soft close, which i effing LOVE
drawer pulls are extra for chinese cabinets, and they are expensive. amazon had the best deals
standard height: my island is ~42" from the floor. standard is 36" which is dumb. my 5'7" wife fought me tooth and nail on the height and now loves it. i'd have elevated all the base cabinets if i could but elevating the stove wasn't something i was interested in because it'd have made a step in the floor so now i have to fight her for the 2 small work spaces at the higher height. "standard" height has not evolved as the population, in general, has gotten taller. at least make the sink taller if you can, doing dishes without having to hunch over is so much less sucky. also i know you aren't all that tall melissa. think about it anyway.
electrical
upgrade beyond what you think you need. we don't microwave, so didn't install a dedicated circuit for it (required by code if you mention it) but i would like to have the extra circuit now. do not install any 15A outlets anywhere. you can by code, but there is no reason to do so. you'll save like.... $200 maybe.
the city/couty whatever will likely require you to upgrade the box. 200 amp is common, at that age you might only have 80 amp. it's money worth spending IMO, we're only getting more hungry for electricity and you'll want the capacity eventually. electric cars are in everyone's future.
structural
you probably have termite damage somewhere. welcome to.... california!
tile
don't skimp on the quality of the actual tile. we cheaped out a bit and went with a builder grade from a box store, it's so far OK in the kitchen but elsewhere in the house the same tile is cracking for no ding dong reason. get some kind of porcelain IMO.
