Wordpress would be my choice.
After getting sick of Wordpress.com, I now self-host mine. I use Nikola, a static site generator that makes things pretty lightweight and easy.
Can I ask how you share it to people? Is it something that you share with people around you, or is it something that you share publicly, in which case, how?
I’ll usually link new posts on Mastodon, and besides that I’ll send links to individual people who I think might be interested.
It’s not something I try to promote widely – more to share my own thoughts with people I know.
Substack is a popular choice
Medium and Substack seem to be the two big "central" sites, but also lots of people don't want a central site so they do self hosted ones. I use a Ghost based site and it's pretty great IMO.
