Tying to clew plate or arbor?

Is there a standard knot that is used when tying an operating line to an arbor or an operating line to a clew plate?
O.K. Since no one else has replied to you yet, I'll play the jerk by replying: Yes.
Optimistically someone more helpful will post soon.
Perhaps Ethan or @whatrigger will stop by.

I think the real answer is in knowing the de-rating percentage for each knot you might choose to use.
A clove hitch is a wonderful and efficient knot but you're not going to be able to tie one in most clews. A properly tied clove hitch reduces a ropes working load to 75% whereas a Bowline or figure-of-eight reduce the working load to 60 and 64%.
Your best bet, but not always an option, would be a properly executed Eye-splice with a thimble. This technique only reduces a ropes working load by 5%.
So the answer is not really, "Yes and here it is!" It's more a series of questions about the load you wish to carry, the rated, working load of your rope, and what you know how to tie.

And don't forget the thimble, or possibly a shackle, when tying to a clew plate.

Most hand lines on arbors will be attached with two half hitchs and the tails taped to keep everything tidy. This certainly isn't the most efficient knot, but also remember that most counter weight systems are design to be dealing with a maximum out of balance weight of 50lbs. See image.

On a clew might be a different situation, as your most likely to find more load on the lines. As @Van said, knot efficiency is the determining factor. To muddy up the water a little more, the size and rope material will change a particular knots efficiency. For instance a bowline can be anywhere from 50% to 67% efficient.

Agree with 2 half hitches and tape the tail
