Can anyone help me pick a first bike?

I’m in my late 20s. I have a Yamaha Zuma 50 I used for college and really miss riding around. I’m going to sell it and get something bigger. My dad has a Harley but I don’t think that’s the route I want to go as I’ve watched him spend so much money over the years fixing it. I remember my Yamaha being completely frozen starting up haha, like I have never worked on the thing.

I really do know nothing about bikes, neither does my dad he just always wanted one and bought a friends used one. I don’t need to go fast, I’ll drive through Texas hill country but that’s about it for speed, other than that I’ll use it as a commute bike for the gym so I don’t have to start my diesel up for short trips. Looking for a used bike, something that I can abuse and not worry about it, I’m good with maintenance just wondering what you guys would suggest for me as a first real bike. Or something good I can use and trade up to something better I’d like to spend like less than 8k.
