Is a Middle East deployment worth jumping onto a new unit (or just going over there in general)?

That's too big of a question, you should narrow it down. For example, one important factor to consider is where can you be of the most use? I recommend making this question a priority. This is a long-term military perspective that allows us to stay flexible, adaptable, and resilient.

When I was downrange I did a lot of work with the MP's. Good times, good people. Talk to your chain and see if they want you around for upcoming operations. You have Joes? Get their two cents.

Ask for a POC at this other unit and make a few calls. If your priority is "Where am I useful?" Then you will ask them questions about what they're looking for in a team and what they're hoping to accomplish down range. Then, you can effectively gauge where you fit in.

There are three pillars of leader development. I think these are overlooked a lot. One of them is the operational domain. The only way to develop in this is to be engaged in unit operational functions. This would be training in JRTC or a development. I can tell you that I have learned from each of my deployments. If you want to learn and excel in the military this would be very beneficial for you. If you have a civilian career that would be damaged by it then I don't know if it would be worth. I did 10 years in the guard. I left the guard due to wanting to move further in my military career to be active. I found that my guard time was damaging my civilian careers.

That's really a personal question because what us worth while for one wouldn't be for another. Kuwait isn't a hotspot of activity that it once was but it could possibly put you hotspot adjacent in case something pops off. For Guard units it's definitely an experience that the younger folks may be jumping at if they missed the chance to deploy during the 20 year GWOT train. It just depends on if it is something you want to expose to you and your family.
