Personally, I'd take my trusty AspX, an AFMU, at least 2 heatsink launchers, ADS, DDS, an SRV, no weapons, lightweight shields (for returning to the bubble), a good fuel scoop, and a docking computer (for when I finally return and don't want to worry about docking). I made it all the way to Beagle Point and back with that load-out and a 32 lyr jump range. I only needed jumponium once on the way out there and twice on the way back.
It wouldn't hurt to do a bit of engineering on your SFD to get the range up and to reduce the weight of some of your equipment. Most of your modules should be D-grade to save weight, but take the biggest A-grade scoop you can fit (since you'll be doing a lot of scooping).
Taking a second smaller AFMU is a good idea, since you only really need it to repair the other one; use the bigger cargo slots for more important stuff.
