Good move or should I stay in NE?

Hey everyone, I'm a 33-year-old single guy from Massachusetts looking to make a big change and move to the Olathe, KS area. I've never really left my area much and I'm pretty sheltered/simple, so this would be a full restart.

Quick background: Hard worker, never call out, outspoken and honest. I rarely drink and stopped smoking weed over a year ago.

Have Ollier's disease (bones are fragile), so I'm careful about jobs that involve a lot of driving or heavy physical risk. Not a big food or sports person

Worked at Walmart for many years. The store here fell apart after a lot of people left, so I'm ready for something new. I can transfer to a Walmart out there and keep my current pay ($21/hr) + benefits.

Stock market and trading is a hobby that helps with extra money.

Looking at apartments in the max $1,500 range. I have a car and am fine with 20–30 minute one-way trips.

Timeline is flexible — sooner would be nice but not urgent.

I'm mostly looking forward to a change of scenery from New England. I don't need a ton of nightlife or activities — I'm a pretty boring/simple person and don't do much even where I am now.

Locals — what should I know?

What's the general vibe/pros-cons of Olathe for a single guy in his 30s? I know its more family area

Realistic cost of living (rent around $1,500, groceries, etc.)?

Any red flags or recommendations with apartment complexes in that price range?

Job market beyond retail/grocery?

Healthcare access (important because of my condition)?

General traffic, community, winters, or anything else you'd tell someone moving from up north?

Any advice, warnings, or recommendations are really appreciated. Or tell me your state is full and I should stay where I am lol. I have options. Thanks in advance!
