There's future tech and then there's future tech. I see the FSS as a powerful optical. radio, and gravimetric telescope - things we already have today (unlike FTL travel, which is pure magic by today's standards). Since you earlier shared your ideal exploration mechanics, allow me to share mine:
1) No honk. The honk is a vestigial instrument from pre-3.3 and needs to go. Instead, we should be forced to fly a lap around the sun, during which time the FSS passively scans the sky for signals, observing parallax which will allow it to identify what the honk currently identifies.
2) I do agree that our computers should be able to see that cool things like ELWs, black holes, etc. are in the system and notify us (like SETI). Once I do the loop (during which I'll also be refueling), I should get a HUD display of the spectrometer along with a message if an ELW is in the system.
3) I like playing the 2D blob game, as this is me using my highly advanced space telescope to zoom in on these objects to get additional data and populate the system map. This is similar to RL, as NASA can scan large swaths of sky, but they need to "focus" on a very particular place in order to observe things like asteroids, and that's why so many near-earth objects go undetected until the last minute. This is the "FSS minigame" that I personally enjoy.
4) Keep FSS details about geology, biolife, and materials to a minimal, like "life detected on planet", requiring us to probe the planet to learn more.
5) Once we do probe the planet, any life documented in the Codex should be identified as that specific life instead of generic "biologic POI)". If I land to find yet another Bark Mound, I'm going to scream. This means "Unidentified Lifeform" should make us jump up and take notice.
6) Allow me to hire an NPC to do most of this work for me if I chose, with caveats that NPC will be slower than I am and will take a chunk of any earnings I make for my discoveries (an idea debated to death in a different thread).
Reminder, I'm not expecting the above things, just saying what my idea of a "perfect" exploration system would look like, and it's pretty darn close to what Frontier already gave us.
