recommendations of documentaries that showcase mundanity in incredible ways

I’m a filmmaker, and I’m interested in branching out into the realm of making a documentary, which is something I’ve never done before (not successfully at least lol). I’ve watched a lot of spectacular documentaries (some that come to mind include Gimme Shelter, Grey Gardens, 20 Days in Mariupol, Koyaanisqatsi, and a personal fav of mine, The Blues According to Lightnin’ Hopkins) - however a common trait I’ve noticed about most of these films is that they usually center around subjects or ideas that are either culturally obscure or grandiose in scale.

personally, I’m more interested in making a film that portrays an extraordinary story of an ordinary person. I have a few ideas for topics but I’m not sure how to present them in an engaging way. can anyone recommend any documentary films that showcase the day-to-day lives of regular, common-folk subjects, and are also outstanding in their execution (preferably on the channel as it’s my only streaming service)?

also if there’s any filmmakers here with experience in documentary filmmaking, feel free to drop any advice or tips :)

TLDR - looking for documentary recommendations about regular people that stand out in their formal execution
