Good neighborhood for transit to both Addison & UTSW?

My partner is considering taking a job around UTSW, but we live in McKinney and the commute is horrendous. I work near the Addison station, so I'm wondering if there are any good walkable-ish neighborhoods in between Addison and downtown Dallas?

Looking at the DART line, intersections with the Silver line seem convenient. CityLine is okay (see note below), but it's still over an hour to reach UTSW for my partner. Downtown Carrollton has 30-40min transit commutes for both of us but from my experience there it's kinda boring and much less walkable.

So maybe having both of us use transit is too strict? If I consider having one of us commute by car then what options does that open up?

Addison is an obvious option where I'd walk/bike and my partner can have a 30-40min drive. But even though Addison circle is there, the rest of the area doesn't seem that walkable.

I'm not familiar w/ the neighborhoods in Dallas proper, are there any good options? We're both around 30, no kids, and don't go out drinking much.

note: yeah i don't consider cityline truly that walkable either but it's still somewhat close to our existing family and friends.
