Basically just wondering how sensible my current card plan seems

Hello, im 22 and quite new to credit cards. I've been building my credit off of my car loan, and I just got a Chase Freedom Unlimited card. I also have the paypal debit card. I am looking to possibly add one to two more cards.

Currently i think it would be good to get a citi Custom Cash for my groceries and then possibly a WF Attune for my gym subscription and maybe one or two of my other "leisure" subscription payments.

Mostly just curious if this seems like a sensible direction to go in as i have no one to talk to about finances and wanna make sure im not missing some obvious mistakes. Thanks!
