I’d avoid Mudd and Colorado College. These are LACs which means there are no grad students on campus and you will definitely be the odd man out. That gets old pretty fast, I imagine. At schools with a large grad student population, you are likely to find more people who are ‘like you’ in terms of life experiences, even if they aren’t undergrads. There will also be grad student housing and reduced rate childcare resources on campus which you may be eligible for - and need given how expensive housing and childcare can be in many areas. (Stanford has both amenities - and a history of admitting non-traditional undergrad students: I had a middle-aged nun and a 50 year old+ airline pilot as class-mates when I was an undergrad.)
Otherwise, your list looks good. Maybe add one or two more in state options to replace Mudd and Colorado College.
