With your level of experience, you should not make the mistake of jumping on, or off, a particular technology stack's bandwagon. Look, lots of worthwhile work happens in .net, and in Java, and in Python, and even in older languages. When the technology in a stack has inconvenient or irritating aspects, that's a big opportunity: if you're good at dealing with that stuff, you're valuable.

What counts? Getting stuff done, not indentation styles.

If you don't know SQL, now, while you're looking for work, is the time to learn it. Give yourself the assignment of building a program and maybe a web site to browse some kind of open data. (Historical weather measurements? Nursing home quality scores? Political donations? There's tons of open data available on the net). Get your system working.

For $10 a month, you can subscribe to an online books service like Safari Books. That should allow you to overcome the somewhat chaotic state of online teaching materials for popular software stacks.
