Bambu and Prusa are the two default picks. They're both very common choices for first 3D printers, they're both about as high quality as you'll find without spending substantially more money, and they're both about as idiot-proof as 3D printers gets. I personally prefer Prusa as a bit more open and good for hacking on, but Bambus target end users a bit better and have their own advantages. You can't really go wrong either way.

I will say that the answer may change a bit depending on what you're hoping to print. If your goal is, for example, high detail miniatures for tabletop gaming, you may want to be looking into something like SLA printers. Or if you need a specific exotic material, or if you anticipate needing multiple filaments, the answer similarly changes.
