There are a plethora of topics about what a senior frontend developer should know. The developer gets judged by the complexity of the nature of the project he has worked on. Here are the topics that I would expect a senior frontend developer to know.
Why topics for senior frontend developer?
Why topics for senior frontend developers?
I would write a blog post targeted at senior frontend developers because the potential of a senior developer is enhanced or limited by the project he works on. Let's say the tech stack of the project is a CMS like WordPress then the developer thinks that's all it takes to be a senior frontend developer. This post is more like normalizing the senior frontend skillset.
What are the tech or libs a senior frontend developer must be familiar in 2021.

The life of a senior developer is never easy because there is a lot to know and perform. Here are a few more things

The list seems too lengthy, what should I do?
The bad news is that the list mentioned above is not complete in itself. I did not talk about cool things like automation, web security, web assembly, etc. I did not talk about rocky topics like office politics or getting stuck on a tech stack due to org policy etc.
You can leverage on what you know already while you are keeping up with the happenings in the community.
Which websites should I refer to stay updated
I recommend bookmarking a couple of websites that you find useful and visit them often. Most websites are going to touch base on topics at a basic level which is not quite useful for senior-level professionals.
Invest and find out the niche blogs or publications. Of course, reading books is a great way to stay updated. Writing some code every day is still a good idea.
say hi to open source or problem-solving.
How do senior-level developers manage their time.
As a senior-level dev, I see a lot of developers swamped at work. To escape the swamp they tend to take a vacation yet attend meetings which seem to be an oxymoron. Here is what worked for me.
More than managing time, we need to be good at drawing boundaries around our time, choices. Build a not-to-do list.
I do not prefer to attend meetings in the evenings or at night. I use this time for something like blogging, reading, etc. Be ready to close the door and work, when your family members think you have worked enough for the day. ss
