Any recommendations for softwares to play around with?

I got a NooSDR (€30 ish on amazon). I agree so much that its 1090MHz(?) leaves so much to explore, but I didn't have much luck other than decoding TV/FM/DAB using CubicSDR, GQRX, and VLC.

I am more interested in using it with Python/GNU Radio so didn't bother installing those super cool web based tools yet. Since I'm just starting, I'd like to get a feel of using it with a general purpose "summary software" first. Essentially something that can lookup the frequency databases, etc. to tell me: what is it that I'm looking at; if its LSB/USB/FM, and these sorts of things. Overall, I quite enjoy CubicSDR for this, but I'd appreciate if you have suggestions or resources I could check out. Thanks for the info above!
