But when I barely touch controls for ten minutes while doing multiple jumps, how is that fun?
Yep. This is the basic problem with supercruise - it works really well in the inner systems where you've got planets to route around, various strategies to optimise your acceleration and deceleration, risks of interdictions, and so on ... it works incredibly badly for the journeys between widely-separated binaries where there is literally nothing you can do to speed up the journey, basically no risk of interdiction because of how the acceleration/deceleration curves work, and you're just looking at a slightly fancier version of the Windows 3.1 Starfield screensaver for 15 minutes.
Veteran players have developed various workarounds to deal with this:
1) You can not go to those systems or stations - after all, playing the game is optional. Some missions tell you in advance ... other mission types don't and must be partially or entirely avoided. If this doesn't seem satisfactory and you can't see how a twenty-minute hands-free journey adds to the experience of doing a surface scan mission when the previous surface scan mission didn't require it ... that's entirely valid and I can't either.
2) You can (eventually) buy a Fleet Carrier, which allows you to directly jump to any planetary body (with some downsides, though, and expensively)
3) You can move to Colonia, Pleiades, Witch Head, or some other region where all the stations were individually hand-placed by Frontier after the start of the game [1], and where long supercruises are rare or non-existent. This was my workaround for it

4) There is a possibility that Apex Travel - available in the Odyssey expansion coming up soon - may shorten the times required for some of these journeys. There's not enough information to be certain on this.
Note that these are all workarounds, not a claim that flying hands-free for 30 minutes is actually fun or compelling or adds to the game.
Compare it also with inter-system travel - the galaxy is big, it takes many hours to get across it, but there are strategies to speed that up significantly, it requires frequent hands-on (if a bit repetitive) gameplay, falling asleep for ten minutes will damage your ship, and you won't get a surprise 20,000 LY trip put on you by a mission (you can take missions that long, but they're all signposted as being that long on the offer screen). Also, 99% of the gameplay is available in or very near the bubble without any long-range travel at all.
[1] It's pretty clear from Frontier
not hand-placing things in places where they require a long supercruise, over the last several years, that Frontier acknowledges and understands this is a problem. The tricky thing is finding a suitable gameplay alternatives - allowing arbitrary jumps (without the limitations of a Fleet Carrier) would break a lot of the
working gameplay associated with the shorter supercruise distances around a single star and its planets. But they definitely know it's an issue and have certainly done things to mitigate it a bit.
