I don't watch a ton of anime myself but I did start out with Full Metal Alchemist and Death Note.. In my opinion I think those two are good for beginners, they were good for me!
Are you looking for something to get invested in or for something kinda quick? Some of the series mentioned are multi-season on-going shows! The standard length of a season of anime is around 11 or 12 episodes total, with each episode being around 25-30 minutes long. Just in case length is something important to you!
I honestly would recommend getting started with watching a popular dubbed show (like Pokemon), as that's one of the main ways people are exposed to anime in the first place. Pokemon overall is pretty episode-driven so you can usually jump in anywhere and still enjoy the show.
