We live in an age where everyone is over-exposed, so you're better off accepting that people have flaws and picking someone that fits within your personal goals. In that case:
General Well Known Person:
Dalai Lama
"Popular people:"
Joe Rogan for the comedian types.
Lex Fridman for introverts wanting to get into engineering and anything related.
Mr Beast for genuinely a nice guy so far.
Gordon Ramsey if you want to be a restauranteer and all around business man. Gordon Ramsey also could probably beat up the majority of everyone named here too.
Terry Pratchet/Stephen King/Brandon Sanderson/Niel Gaiman for the writer types
Magnus Carlsen for Chess players.
Brian Greene for theoretical physicists
Shigeru Miyamoto for video game types, thought Satoru Iwata was a better example in many ways.
Graham Hancock if you want to be someone that will get laughed at by every person in a field of study but still persevere.
Now, there are some other role models people pick but things get crazy depending on how you feel on some matters.

Kanye West
Any rock star that still manages to have a following
