I have only ever seen Madoka

It sure can't hurt!

I have been considering just diving into the original sailor moon and cardcaptor sakura

And certain seasons of precure are catching my eye

I haven't seen all of Cardcaptor, but I've enjoyed what I have!

I've only read the manga, but Shugo Chara was a fun time, too!

ooh!

highly recommend Sailor Moon, for sure. I also really enjoyed Pretear, though that could potentially be divisive given some of its imagery/symbolism and the very mild harem anime vibes
