I would definitely go AFMU over shield, if only for the added range (both jump and endurance). As long as you dock at a Scientific Outpost and upload your data in a border system with only NPCs, then CMDR in open shouldn't be an issue.
If you just want to evade CMDRs in a small explorer ship, I'd recommend a Cobra. It has smoother Super Cruise agility, less engine jutter, about the same range, more relaxed speed scooping, and and similar heat tolerance. The slightly longer range on the Scout is nice, but scooping is a bit of a headache imo and not worth the annoyance for most people, nor is the compromised explorer loadouts, or the reduced speed/survivability in human space.
