As others have said: build a moat.
Most of my bases; main and forward bases, have moats and they block pretty much everything.
Late game mobs can still cause issues but trolls are defeated perfectly.
Trick really is to learn from history; build on a hill, build a moat, only 1 or 2 small access points and double gates offset with a distance between them.
My main village (it’s far to big to be a base these days) even has free roam wolves outside and wolves breeding in its moat.
Raid and mob fighting is now my choice; I can Wade in for supplies or just sit back and watch or just ignore them
