Or, perhaps experienced users can tell me that the tuning works
quick enough that even if I try to confuse it the KAT500 will be
quick enough that it isn't an issue.
Since there is no overlap among the 160m inverted-L, LPDA (20-10)
and 6 meter Yagi, I would put them on the manual switch on one port.
That would leave the vertical and dipole on their own ports.
The KAT500 memorizes tuning by band and port so you should be able
to recall the memorized settings for frequency/band without any
confusion when selecting antennas/bands.

Currently I have five antennas connected to my K3S via a manual switch:

Vertical, CW on 80, low end of 40, 30, 20, 17, 15, 12 and 10.
Dipole, Phone on 75, phone on 40, 20, 15
Inverted-L on 160
Yagi on 6
Mostly the antennas are below 2:1, but they need some flattening on 160, 80
and 40 if I have to go beyond their sweet spots.
When I build the KAT500, what is the best use of the 3 ports available to
maximize it's tuning algorithm? In other words, how can I maximize the
likelihood that a band change or QSY will result in a rapid tune due to
prior memorization, versus a somewhat longer full tune?
My thoughts were perhaps to put the 6 and 160 antennas each on their own
KAT500 port, then use the manual switch for the three that would cover HF.
Fine, except there could be a situation where the KAT500 had memorized a
tune for 7.100 that might be fine for the vertical but different for the
dipole. The vertical is omni, so at times it would be a better choice than
