Newspaper archives are great to look at random events and also see how people at the time reacted to them!! Maybe old magazines/films could be cool too?
There are also so many different blogs on Substack which look at different bits of history - like https://www.africanhistoryextra.com/?utm_source=global-search, https://florencehrs.substack.com/, and https://15thcfeminist.substack.com/. Definitely browse on Substack to see what's on offer and what style/topics interest you the most!
For more general blogs, https://publicdomainreview.org/ and https://daily.jstor.org/ look into quite niche topics.
Also the podcast 'The Rest is History' has done loads of episodes on many different topics! Have fun <33
