There are a few exceptions, but most entries in the genre are sort of trite and bland. They're too safe, I guess.
Some examples:

Although it's all very content dependent of course - FE development tends to lend itself a bit better to this sort of format.
Here's are some of my favourites.

I always feel bad for company bloggers nowadays because it usually seems like an engineer has to talk marketing blargh and it seems like a nightmare to spend time with comms to make what’s interesting to me cleared and understandable by everyone.
To capture and share info, just start with an internal blog and write up all your meetings. I did this although it’s hard to measure success as people read it and use the material.
The reason I don't is because those blogs only rarely actually talk about anything of interest to me. Usually, they're mostly marketing with a veneer of tech in them, or they tend to focus on things only of value to those who work with or at those companies, or they just talk about common engineering topics.
Very low-value stuff (in terms of what is valuable to me). I can put my time to better use.
Even the slightest friction makes the engineers not want to bother.
We've made a pretty successful engineering blog at blog.doit.com. I've published more there by far than in any comparable period of my career
Rather Labs has one, for example: https://www.ratherlabs.com/blog
I encourage you to start your blog and share your knowledge with the community! Best of luck!

There's also a service that does "corporate eng blogs as a service" - though I can't recall the name and can't find them on google. Pretty expensive though.
I think starting by posting the slides from the talks seems good.
