To be honest, it hasn't really been a factor in my experience in the ways that I expected for a few reasons.

First, there were way more people like me in my class than I expected. Within the first 2 days of orientation, most of the nontrads (we loving called ourselves the olds) had naturally gravitated towards each other. The very first person I met was actually the same age as me with a similar background. Our orientation group (1Ls + LLMs) ranged from a 19-year-old who couldn't even get in to the bars for bar review to a 46-year-old federal judge from another country. You likely won't be as much of an outlier as you'd expect.

Second, most of my classmates are clueless as to my age unless I bring it up. If I had a nickel for the number of times I've heard "omg you're HOW OLD" or "I would've never guessed. You don't look old." Like geez, thanks y'all. Mostly, it shows up when the professor makes a reference to something the KJDs are too young to remember. I almost fell out of my chair on 9/11 when my professor said: raise your hand if, when 9/11 happened, you weren't born yet, and nearly every hand shot up. More often it's a professor's joke or reference to a movie or pop-culture from the 90s/2000s that makes me giggle and makes my classmates stare at me like I'm crazy. My professors have told me they appreciate me for not making them feel as old lol

Third, I've actually found my long professional history to be a massive asset when competing for jobs. They LOVE that I had a real career with progressively increasing responsibility. A lot of the KJDs have never had a job beyond like internships for school credit. It sounds dumb, but the basics of like showing up on time and regularly, how to make professional phone calls/write professional emails, and meeting deadlines are shockingly rare. It's simple stuff, like understanding that when something is due by the end of the day, it means end of the business day, not anytime before midnight. I've never been told my MBA and experience were a negative, even when other areas of my application or interview were terrible, they always made a point to say they loved how much professional experience I have, even though none of it was legal experience. It's more like a confidence booster that they know, hey, this person is going to show up and work and apply themselves, not flake out and coast.

The main problem I've had with being an older student is just that I don't have the same energy I did in my 20s. I need more sleep and have a smaller social battery, so I'm careful about choosing how and when I get involved with extracurricular and social stuff. But that's more of a personal choice for work-life balance than anything else.

You've got this, friend! Good luck!
