Screw pillars with 4mm banana sockets in the centre.  Available in a
wide range of colours, rated to 500v and 10 amps.  Easy to fit, easy to
plug-up and easy to see what you are doing so you don't make silly (and
expensive) mistakes.
 

 
We are just talking about something simple like this, right?:

They would be perfectly satisfactory if you were happy just using plugs.
If you wanted the option of using bare wire ends, you could try:

If you choose to use a binding post, consider their spacing; first, you want
to be sure you can get your fingers around them to tighten/loosen them
comfortably.  And, if they support banana plugs, consider spacing them
to support "dual" plug assemblies:

It's one of the physical constants of this universe that banana jacks
are always 0.75" apart.

 
...except in pre-war Netherlands, where they were 1-inch apart.

 
Surely you mean one meter.
 
But which war?
 
 

Well, they are banana jacks, so they have to be usable by monkeys. (*)

(*) Ancient IBM joke: “Our machines are so easy to service that a monkey
could do it!” “Is this a one, two, or three-banana job?”

(The “🍌🍌🍌job” became proverbial.)
