if you're talking home defense probably your best bet is just an arming sword. you can stab and slash, and it's made to be used 1-handed and quickly, the weight is balanced better than the machete / cutlass so you can strike quicker. i wouldn't want to go through a hallway / doorway against a cutlass but an arming sword is more versatile, you can just flick and stab at them effortlessly too fast for them to even see.
