My bike has points,
It isn't required for points
So is the "SPARK PLUG CAP NGK LB05F" not suitable for standard applications?

Any 5 KOhm resistor plug, cap or wire isn't unsuitable
for points or e.i. that doesn't need it. It just doesn't provide you or your motorcycle with any benefit either, but is something else to go wrong.
I'm trying to source an NGK equivalent for the original champion caps/leads.
Depends what "the original champion caps" were.
On my Triumphs, they were simply a cover over the lead's attachment to the plug, so no resistor plug cap can be an "equivalent".
If your local laws required the original caps to be resistive, it can only have been to prevent interference with nearby analogue tv and radios. If you have violent neighbours still using these nearby then maybe your bike does need resistive plugs, caps or wires ...
Do they have to be 5K or will 10K work as well?
In an electrical circuit, while some resistance is necessary to prevent it being a 'short', 'more is not
good'. Electrons will always take the path of least resistance. The spark plug air gap is already a huge resistance. If you keep adding to it, eventually the HT will find another path. Then, not only won't there be a spark at the plug, if the path the HT has found is through some electronics, that faint smell of burning is always expensive.
That's also why e.i. makers always advise against disconnecting the HT when the ignition's working.
