I mean, these suggestions only fit your specific criteria. There are much, much better animes out there, but generally aren't much in the way of 'cute'
Ie cowboy beebop, trigun, gurren lagann,, ghost un the shell sac, etc.
Not really episodic anime but the Miyazaki fulms are pretty great (understatment) and theeyre cute too, in the 'childlike wonder' sort of way
