Welcome!
Right now I think Primal is the best place to start. It's easy, it's got a built in lightning wallet, gives you multiple options on how your feed looks, and the mobile app keeps you off Global. but after that it depends on what suits you. I like Amethyst on Android and Nostur on my Mac, and all the webclients generally annoy me but  Nostrudle and Coracle both have features I like.
But everyone is different and being able to control your experience is what makes nostr great.
