Since Everyone's Enjoying the Horsie Game: What are some Recommended Gacha/F2P Games?

PC or console options only, please. I've dabbled with Genshin Impact and a tiny bit of Honkai and Zenless, but those are full-fledged RPG timesinks that I just can't muster the time for, at least currently. I'm also still on Nikke's tutorial so I'm not sure how I feel about that one yet.

I want stuff that's easy to pick up and play and generous with the gacha stuff so I don't feel I have to endlessly grind just to make progress on the story (assuming it's a story worth following).

Also if I were to devote time to one of the Hoyo games, I would like to know which one stands at the top of the Big 3. Or 4 if we're counting Impact (which I would have given a shot if it were still possible to nab Asuka).
