Asking for martial arts recommendations

So, I want to do some martial arts, for self defense. Ideally one that will be useful without giving me CTE, or any long term bad stuff, even though I feel this is already asking for too much

I don't live in the U𐓏𐓏 so gun related stuff isn't really an option.

I'm somewhat heavy, with a year of experience in lifting, and my cardio is not the best, but I can do long walks (of 1 or 2 hours) before getting tired.

I'm going to move to a bigger city in September, and there's a lot of stuff available, so you can comment on the more niche options.

So yeah, any advice from your experiences is welcome lol

If I had known people started arguing over my post I wouldn't have made it.
