I wouldn't normally do this, but I'm calling it first commenter privilege? :-) For the past ten years, my full time job has been publishing weekly developer newsletters, now going out to nearly 500k subs a week. I won't link them all as it'll take too long, but things like https://javascriptweekly.com/ and https://golangweekly.com/ are our bread and butter. https://weekly.statuscode.com/ is our weekly overall programming world update. We have lots more, but generally if you Google "[technology of choice] newsletter" you will find interesting stuff from all sorts of people :-)
To answer your question as to which newsletters I enjoy, I really like https://podnews.net/ because I'm heavily into the podcasting ecosystem and he rounds it up really well each day.
