You can fortify the benchs or put in the ground, just be sure its not destroyed by the raids or greydwarfs. One brute destroyed a bench, I didnt notice and suddenly there was like 4 night fulings and 1 deathsquito that almost killed me (bronze armour).

I've seen yt tests and it was said benches, chairs and tables doesn't prevent spawn of mob. So I'm not sure to this one.
