It sounds like you value time and flexibility more than additional money. Overall there seems to be more to lose (flexibility and time) than gain (money) by switching jobs. You could always look but here’s my advice as someone who took more pay with less flexibility. Be extremely open and upfront about what you want, this is as much a part of interviewing and negotiation as the salary. Explain what’s important to you as far as flexibility, and if you take the job, hold them to it.

When recruiters contact me there’s two things that I find out before having a conversation, what’s the pay and what’s the flexibility/PTO like, they like to stretch the truth but it at least saves us both some trouble.

P.S. You hit on the marginal utility of money, it’s a good economic concept to be familiar with. Essentially, the 99th to 100th bite of dessert is minimally better, but that first bite is wonderful. The $20,000 more won’t make a big difference if you already make 250-300k, but if you only make $10,000, $20,000 more is a massive improvement in your life.
