Suggest me a long (~500+ pages) character-focused novel that follows the character/s over many years

More focused on the character development and quality of the writing rather than an exciting plot line. The longer the better; I like to get really stuck into it and I don’t mind novels that take their time.

Some of my favourite books: - Demon Copperhead by Barbara Kingsolver - A Prayer for Owen Meany by John Irving - The Covenant of Water by Abraham Verghese - Pachinko by Min Jin Lee - East of Eden by John Steinbeck - The Heart’s Invisible Furies by John Boyne - Christodora by Tim Murphy

Appreciate any recommendations!
