I remember John Carlos Baez having some interesting stuff: https://johncarlosbaez.wordpress.com/

Some other ones I had bookmarked the other day but haven't seen much in depth, mostly computer science based but more towards theory/math side:

https://blog.computationalcomplexity.org/

https://semantic-domain.blogspot.com/

https://greydanus.github.io/

Also go to Terry Tao's blog and look at the sidebar, there are a lot of links to external blogs there.

Posts irregularly, but I've found https://mathwithbaddrawings.com to be good.*

There's also https://phys.org, which aggregates content on lots of things, including physics.

https://www.symmetrymagazine.org/ looks relevant, but I don't read it that much (not because it's boring but just because I don't find particle physics interesting)

*Tracker warning: https://themarkup.org/blacklight found 92 ad trackers and 274 third-party cookies if you were on a desktop in someplace like Ohio with poor privacy laws.

Not sure if this is what you want, but I like:

The post of Mathologer about 1+2+3+...=-1/12 , probably https://www.youtube.com/watch?v=jcKRGpMiVTw

The post of Minute Physics about the Higgs Boson , probably https://www.youtube.com/watch?v=9Uh5mTxRQcg
