Driving a car to get around gets me much more time with my friends and family and myself.

1. Weight: I've been 50+ lb heavier than I am now and I, personally, hated it. It makes everything harder and that only gets worse with age;
2. Fitness: this one is (IMHO) less extreme than weight differences but if you can't walk up a flight of stairs without getting winded that's going to impact your life in negative and real ways;
3. Health: when you're young this is less of an issue but as you get older being overweight and/or unhealthy becomes a more significant risk factor for many health problems. Heart disease, strokes and a host of others;
4. Quality of life: getting fresh air, sunlight and exercise is generally good for your state of mine. At least, it's good for mine. It can help put thing sin perspective (professional and personal) and improve your mood.
YMMV
As far as time goes, this was a big motivator for IF for me. As in, the effort of preparing (or even buying) meals annoyed me. It's one of the big things I appreciated about working in tech: the free meals. Not for the quality necessarily but primarily for the convenience. I don't have to plan for (many) meals.
Treating eating as a leisure activity can be a trap too like some people have weight issues because they like food and end up treating it as a reward, which reinforces the cycle.
I prefer to think of food as necessary fuel.
But how much time do you spend on food?
At work I became more productive because I wasn't struggling through half the day feeling fatigued and worn out, or pushing into a panic attack from all the caffeine needed to keep me conscious. Outside of work, despite (and as mentioned in many cases because of) the exercise I spent more time with friends and family. And I probably bought more than 2 years at the end of my life. I was on track for a heart attack in my 40s the way I was going.
I'd strongly recommend finding some sort of physical activity that you enjoy, rather than seeing as a chore.
I think if you've made the choice to just not exercise you should be honest about why instead of inventing non-problems like exercise significantly reducing time spent with family and friends. I literally don't know anyone who has ever raised this as a problem. Maybe if you're exercising as an Olympic athlete...?
This specific amount of cardio fitness is probably not strictly needed. Given the choice I believe most people should chose more strength training. But at any given time, being able to pop out at least a 5km run or equivalent is probably a good place to be.
