I like an oil if I am changing tubes frequently, but anti-seize lubricant (a lifetime supply can be had at CanTire in the automotive area) if they are only going to be used or removed every 4-5 months. I found it doesn't take very much anti-seize ( or oil) to allow them to be exchanged. The oil is much cleaner, in my opinion, and I have to be careful not to get the anti-seize lubricant all over myself and gear! It is quite messy.
Storage environment (damp - dry, etc) seems to be a factor.
There are many on this forum with more experience than I have, but they might agree that chokes should be re-lubed if they seem dry and difficult to remove, or if water has been a part of the day's experience. They might have more and better info for you. I could be wrong ( for the millionth time!) If you never lube the chokes, you will probably be in trouble eventually.
