Ah the age old debate.
Though I'm not really sure what your issue is. You get bored of exploring things quickly, but say you need a huge jump range so you can go really far away to explore things. But then you just have further to travel back when you get bored

Not all ships have Guardian Boosters, I spent the first couple of years of this game with only a 35Ly jump range on my Asp and went to Beagle Point with it in that time, I only got a Guardian Booster when 3.4 dropped last December. Long jump ranges aren't needed for Exploration unless you want to reach the very outlying stars, especially since Synthesis was added. And Exploration isn't about getting as far as you can in a short space of time.
Exploration is pretty much what you want to get from the game to be honest. For me it's exploring systems to find interesting views, or strange planets/stars, or more recently various anomalies. You set yourself personal goals and go out to achieve them. On the first day of Gamma I dropped my weapons from my Cobra, brought a fuel scoop and left for the Pleiades Cluster, simply because it's my favourite object in the night sky. With an 11Ly jump range I had no idea how long it would take me to get there and I didn't really care, I wasn't doing it to be the first there. Just like my second journey out to the Crab Nebula, I knew I wasn't the first there but I wanted to visit and I was the first person to document the journey.
Sometimes it's something as simple as finding a system with 4 huge super bright stars in it, and one solitary planet. I thought it looked like an awesome place when I first discovered it many years ago, 42,000Ly from the bubble, the sort of place my character might retire to one day. Then when Horizons was added, the planet was landable and so I went back. Then later on it took on a more significant importance to me.
More recently with the addition of the Codex I thought it would be nice to get one record reported in it, just for posterity. Well I found 1, then 6, then I realised there was a gap in the White Dwarf market... Well my ship has a new tag 'White Dwarf Hunter' and I now have 110 records reported into the Codex, 77 of which are White Dwarfs
Now I am back to just meandering my way around, looking for interesting places. So many people are focused on the need for big jump ranges, but really for exploration as long as your jump range is above 30Ly you won't have any issues 95% of the time, and obviously people have done huge journeys with far less. But again, jump range is for the travelling not the exploring. They are not the same thing, neither are they mutually exclusive.
i think sector jumping harvesting materials to jump sectors is just another way of achieving travel for those who hate the repeated jump and scoop.
I hate combat, if I collect enough material can I just count it the same as having killed loads of ships?
Exploration is spotting something in the star scape, on the way and changing course to go see what it is.
Oooh yes, very much this. I have done this many times. The pain in the backside is trying to work out which direction it is in, by targeting random stars on the Galaxy Map until you find one that's in the right direction
