we have hardwood throughout and i love it, but yes, we usually remove shoes and have to be careful, but that ways at least 20yrs later the finish is still reasonably ok. the side room here they used used maple flooring from a gym, but that turned out to be a huge amount of work (every edge had to be scraped to get a good fit again). this side room could now use a bit of a refinish but that isn't going to happen. it was used as an artist studio for several years and some paint got splattered around.
as for the rest of the house and the countertops they are both (kitchen and main bathroom) are the same as the floor.
you can see peeks of the counter in:

the thing about hardwood or tile floors (i'd never do pine, too soft, takes too much damage easily) is that if you drop a glass it's 99% chance it's going to shatter. on carpeting you might get by with a bounce instead of a shatter.
i still would have hardwood throughout, my sinuses/allergies do so much better without carpeting, it takes a lot less effort to dust the floors than to vac.
as for cold floors, that's what socks/slippers are for. i used to hate wearing anything on my feet, but i'm used to it now, in the summer i really hate the feeling of sweaty feet sticking to the floor (or my shoes/crocs for that matter) and that really is where i've gotten into the habit of wearing socks almost all the time.
rugs are too much of a tripping hazard IMO.
if i were splashing a lot of stuff around i'd get a hard plastic floor cover for the area by the sink.
kitchen counter, if wood, has to be really well sealed you want to be careful of knives and setting packages/buckets that might have dirt on them on the counter. we keep old towels around for that and use them a lot.
i think i'm going to have to redo the utility room shower this summer...
