Have you looked into what plans are available to you, and what the deductible and max oop are, as well as the monthly cost? You need real numbers to make a comparison.
I was like your spouse, I never went to the doctor except for the emergency room as needed, so a high deductible HSA plan made sense, and enabled me to build up a nice balance.
Now I'm in my late fifties and needed some work done so I switched to a silver cost sharing plan with a much lower deductible and max oop, and saved about $6k ($2k max oop vs $8k). It's nice that you can switch back and forth, but the deductible goes back to zero on January 1, so don't start getting sick in the fall, wait til spring ;-)
You'll need to fill the family deductible, until then everything is out of pocket. And then you'll generally pay coinsurance, where the insurance will pay a certain percentage of your costs, until you reach your max out of pocket, then everything is covered (as long as it's approved, in network, etc). Sorry if you already know all this, but the max oop number is the most important one. You also need to check which hospitals, clinics, etc are in network in your chosen plan. In my area there are 3-5 different HSA plans to choose from and they don't all cover the same places.
Also, my plans have never covered dental or prescription glasses, that might be something that is covered in your present insurance.
It is hard to know how much you will spend out of pocket because it's really hard to know what you will pay vs what your insurance has been paying, even looking at your bills it's hard to figure out. But try to come up with an estimate.
I put all my medical spend on cc's anyway for the sign up bonuses, and never take anything out of the HSA. In my opinion they are most worthwhile if you invest them long term.
I think of them as an extension of my emergency fund; there's enough in my e fund to cover the max oop in a medical emergency until the insurance starts paying out.
Overall I recommend them, as long as you are able to cover what will likely be a very high max oop in a worse case scenario.
