everything will look dated eventually. be sure to include some whitewashed
shitshiplap.
if you want it to be fashionable for the longest possible time i'd reccommend going with tan, off white, biscuit... those will be coming back into fashion soon i'm sure of it!
your city will have some requirements for various levels of rennovation at the permit office. if you want something to be up to code... read the code and your city will have some additional level of nitpickery on top of the standard codes.
if you're doing countertops anywhere, and want "granite" of any variation (quartz marble, quartzite, actual granite etc etc etc. something that is or is meant to look like stone) spring for the mitered edge rather than the laminated (as most pre-fab slabs are) edge.
some patterns it isn't noticeable, but lots and lots of patterns it looks very obvious and is especially apparent on any long straight section as you'd find in a kitchen countertop. materials meant to imitate something grainy (granite) might be ok with laminated. something with stripes/veins (marble or imitations) will look really weird if laminated
tile: other than large format tiles, farm it out. it's way harder than it looks on youtube. large format tiles are more forgiving IMO. if you have a pattern: seriously, hire a pro.
found a picture, obvious laminated seam. some don't care. looks really hideous to me.
