Folktales are a good source of non-feminist masculinity since most collections were published before it took hold. And who doesn't love a good story? The following tales are recommend for children, though the language is a bit outdated:

"The Four Skillful Brothers" - a quartet of men work together to achieve a goal. (Source: https://standardebooks.org/ebooks/jacob-grimm_wilhelm-grimm/household-tales/margaret-hunt/text/the-four-skilful-brothers).

"Tablecloth, Donkey, and Club" - a boy learns to outwit thieves and get revenge on his abusive mother. (Source: https://www.jstor.org/stable/534339?refreqid=excelsior%3A58412d15f65d03f321f7a419d44d3e01&seq=2#metadata_info_tab_contents)

"The Smith and the Fairies" - a man ventures into Fairyland to save his kidnapped son. (Source: https://sacred-texts.com/neu/celt/pt2/pt212.htm)

Additionally, there are stories with female protagonists that offer good alternatives to the awful, feminist-influenced "heroines" in mainstream entertainment:

"Kate Crackernuts" - a girl breaks a curse on her stepsister and then rescues a prince. (Source: https://www.surlalunefairytales.com/oldsite/authors/jacobs/english/katiecrackernuts.html)

"The Stolen Bairn and the Sidh" - a woman ventures into Fairyland to save her kidnapped son. (Source: https://storytellingforeveryone.net/stolen-bairn-and-the-sidh/)

"A Story of the Oki Islands" - a girl searches for her exiled father and saves an island from a sea monster. (Source: https://www.sacred-texts.com/shi/atfj/atfj19.htm)
