From the OP, my understanding was that he wants to visit particular places and has limited play time.
I completely agree with Satsuma, if you have no specific destination in mind, there's no particular need for a bigger jump range. 100 jumps is 100 systems to scan and explore even if they are only 10 ly apart.
Even if you do have a specific destination or destinations in mind and you have limited time to play daily, there is no deadline.
As I mentioned above, my trip of 207 hours in 10 months is
less than an hour per day on average.
So yeah, you absolutely don't
have to engineer your FSD, but it does make the trip faster if your time is valuable.
For me I've always enjoyed setting a goal to reach specific places instead of just exploring uncharted areas.
Which means I don't really have many unique discoveries of my own, I'm just a tourist visiting places that other people have discovered.
I've done trips to
NGC 6357,
NGC 7822,
Eta Carinae, X Carinae,
Betelgeuse,
HD 49368,
Sag A*, the formidine rift,
the southern edge, and the
M67 cluster.
I just finished touring the sights around the Colonia region like
Monde De La Mort,
Sword of Damocles,
The Mighty and the
Glowbug Giant.
With the exception of the M67 cluster, you can get to all of these places with a 34ly range or even less, it just takes longer to get there.
My first trip to Colonia was in a 32ly DBE but my second trip was in a 60ly 'Conda and I was very happy with the time saved.
100 jumps at 60ly apart is still 100 systems to scan and explore but you're that much closer to your destination.
