Get a 29er. The modern day hybrid. Like I posted earlier my Trek Marlin 5 was at a good price point for me at least with quite a few features.
For the first bike a 29er has 29” tires, normally not as aggressive knobbies, get a hard tail you start spending money on a suspension rear. Get at least an 18 speed but a 21 will give you a bit more mid gears maybe. If you can fit disk brakes in the budget they are really nice. I’d put a springer front down low on the list for a first bike but mine came with it so I’ve got it.
