Commanders,
as a explorer and exobiologist.
The minium amount of optional is 8. That's true. But if you want to be prepared totally, even without 2 AFMU there is nice to have things like repair and research limpets, cargo for "souvenirs" from notable stellar phenomena etc.
And... yes, you can fly carefully, but there are different style. I fly and watch VOD or YT at the same time, landed tousands of times and hitted maybe 3 times, but... it happened. It could happened even if you have 10k hrs of crefully playing, so totally agree about "more than you need stuff" as a "nice to have idea". And I like modules like SuperCruise Assist, because I llike to put SA through the planet and use that time for making tea, dinner, or lurk at some website. I preffer long, slow sessions of game than shorter and more intensive.
But of course, you can fly even Sidwinder all the time.
About large ships for exploration/exobiology. I preffer small ships and flying without SRV, but a lot of cmdrs use universal M-pad phantom or similar. Many of them forget that Dolphin is the best chocie between S-pad and all-might M pad, because of many optionals and decent jump range (like 65 Ly fully equipment). But I had a time in my exploration life when my favoiurite ship was Belgue. It is very good-looking, very luxury and comfortable ship. It is enormous big, but because of small landing gears and a lot of space under it, it could land suprisly good even in the mountains. You don't need a big emptty place for land, you just need 4 small pieces of land, like for 4 simulatenusly landing sidewinders

And literally this is pretty nice and funny way to exploration. I used SLF to find a good spot and then lande them on Beluga and use SRV to find all three probes

(of course i think about lovely fungoida

).
In the Elite lore there is a ship called Boa - it is a larger version of anaconda and have S landing pad, so you can literaly fly above planet surface and use sidewinder to land and collect bio probes
And I wanna say, I can't wait for the new Mandalay ship. This is the situation, when my wishful thinking meets reality

.
I love Zorgon Peterson ships for how they looked. I spent a lot of time doing explo in Hauler, even if I had a lot of money for any ship. It is just so nice to fly. I hope Mandalay will have even more than 9 optionals.
