I made just such a template for myself recently. Sort of Medium-ish, single column; option for full width/bleed image: https://birddive.com/blog.2020-11-8.repurposable-templates.h...
i think a part of that was also realizing what drew me to frameworks initially was less about styling and more about the grid or flexbox etc scaffold - the most daunting part for me to this day. creating my own set of base templates helped me learn quite a bit about grids though, and now when stuff breaks i can tackle it with more confidence in where to look for the issue and how to go about fixing it.
that being said, i'm not anti-framework or anything - i relied on them alot as i learned CSS, and even now i still treat them like something akin to styleguides or catalogs of what's new/trending in webdesign
