you could probably start watching any modern anime that's popular right now and do fine, anime is made to be pretty digestible nowadays.
frieren i haven't watched, but it's critically acclaimed. jujutsu kaisen is very action centered and entertaining. dandadan is fantastic if you want to see something that's really out there.
and for some personal picks:
samurai champloo. this one is cool all around. sick style, great music and animation all mixed with hiphop culture.
mob psycho. unique 'simple' art style with crazy animation. it's a story about self improvement. everyone should watch it
one punch man, also by the creator of mob psycho. especifically season 1. season 1 of one punch man is a gem brought to life by some of the best animators in the industry. easy must watch. it's also hilarious
i'd consider all these pretty digestible too
