First, congratulations about making so much progress, especially with the unanticipated huge medical bills and rise in property taxes. I was confused about the huge jump in gas and drop in car savings, but I'm guessing you have added a second car, since you didn't used to have a car listed as an asset? What is the land loan for? If it was related to the house (i.e., you built in 2019, swapped a construction loan for an 80% mortgage and a small land loan to make up the difference), that makes sense. If you bought a separate property, however, consider selling that, since it's not currently providing any income, and your medical bills make this a bad time for cash flow.
Really, almost everything you have here is reasonable. Yeah, there are a lot of areas you can cut back if you want; groceries, cellphone, internet, subscriptions, charity, and eating out leap to mind, but really almost everything is optional once you get past housing and food. And you are absolutely right that you don't want to cut back to the point of feeling like you're sacrificing important things every day just to maybe be happy in 30 years. So if this is all what you consider to be the kind of lifestyle and budget you can be comfortable on for decades, then that is what you should focus on; sure, you should always look to trim around the corners where you can (and certainly if the medical bills back off you will appreciate that slack!), but this is fundamentally what you should plan around.
The real issue, then, is whether this lifestyle is worth the tradeoff in years to retirement. The problem with saying "I like my current lifestyle" is that it comes at the cost of working significantly longer -- which is also easy to ignore when you're in the thick of it day-to-day. You currently are saving at about a 10%-12% rate (counting both 401(k) and your Roth). That savings rate puts you at 40-50 years to retirement -- see

Now, you are better off than that, because you already have the 2 years' expenses saved toward retirement, which will grow and knock probably 10-15 years off that end goal. But that still puts you around standard retirement age. So the real question that you need to consider is whether all of those other things you are spending money on are worth your DH continuing to work for another 30 years or so?
Another way to look at this, btw, is to realize that you guys are already semi-FIRE: you have quit the day job, and you both decided that that was worth it, even though your husband has to work longer as a result. That is probably the single-biggest luxury your income has afforded you, and the fact that you can do that at all shows that all of your efforts have been a significant success.
Finally: you're right to stop the 529 savings right now. Your retirement has to take precedence. In addition, if you go into the college years still netting around $60K, you will get a very good financial aid packages; indeed, if your kids are smart enough to get into one of the top colleges (and want to go there), there are a bunch that have committed to 100% aid even for families making into the low six figures. Now, those aid packages always include loans, so it's reasonable to have $$ available to avoid those and/or pay for unanticipated expenses. But that's optional, so a much lower priority than all those other expenses that you're currently facing.
