My 2 cents:

Avoid competing with 20-somethings coming out of local coding bootcamps. Here there are multiple groups churning out React + (node or ruby on rails) web devs. Just learning Angular instead would set you apart.

Pick one thing and focus on it. It can be so exciting to learn a bunch of new things but you will end up spread too thin to be of much value. Now that "one thing" can be a full stack of a couple technologies, but pick one of each and specialize in it.

Don't be too niche for your market. If you're in a small market, there may not be a lot of demand for machine learning or rust. A solid .NET dev is likely more employable. Look at open job postings and use them to build up a list of common needs there.

There's a pattern I've seen a number of people successfully follow. Find a somewhat newer technology with good potential value in your market. Learn it. Blog about what you learn. Develop a talk about it and give it a couple of times (Meetup groups are usually desperate for speakers). Produce a video of your talk, either from an in-person event when we can again or one from your desk environment. Start pinging publishers about writing a chapter or reviewing a book on your chosen tech. If possible, get your name on a book cover, even if it's with other authors. From then on, you are "Zero Balance, author of 'Getting Started With Golang Embeds'". Even if you're applying for jobs that aren't closely related, you project a lot more authority than the average coder.
