I've got some good free resource recommendations if you want:

https://wiki.analog.com/university/courses/electronics/text/... - An excellent free "Intro to Electronics" course from Analog. In fact, all of the courses on their website are pretty good, I would say comparable to what you would get at a university minus the TA support when things don't work. But /r/ECE or Stack Overflow can probably help if you ever end up really stuck.

https://www.analog.com/en/education/education-library/softwa... - Another from Analog, it's a great resource for learning SDR. It assumes you're coming from an EE background though, so it would be helpful to do the fundamentals first.

http://freerangefactory.org/pdf/df344hdh4h8kjfh3500ft2/free_... - Free Range VHDL is what my FPGA class used, and it's free!

I would also suggest playing with some ECAD software like DipTrace or KiCAD. It's generally not part of a normal EE curriculum, but really should be! Being able to draw a schematic or lay out a circuit board will be useful if you have any advanced projects you want to try at home. Especially with cheap fabs like OshPark it's a good skill to have.
