Just to add some more data saw someone posted this in another thread it shows how late LL were available for different rides. Of course this is only availability and not return times but MFSR has been available into the afternoon pretty consistently so that may help with your planning. I think what you select as your first LL probably has to combine with your rope drop strategy.

Personally, I like Slinky Dog Dash but I would never wait in the lines it gets especially with the line being outdoors and mostly in the sun so I prioritize it as the first LL even though my return time may be later in the day. Then plan to rope drop MFSR, since most rope droppers are going to SDD or ROTR I like MFSR because it doesn't get as long at rope drop plus it is a ride that is great to re-ride with the competition aspect. Then do some filler attractions (Star Tours, Aliens, Toy Story Mania) to hit the 120 minutes after park opening, hopefully choosing MFSR to rope drop will get me out in less than an hour giving more time to these. Then I just optimize for close return times for things that are gone mid-afternoon TOT, MMRR, RRC.
That is all easier said then done of course with return times but that is just my personal plan till things go sideways
