I like to tin the tips to make insertion a little easier, and it also
prevents the ends from spreading out. However, if you tin too far up the
wire, then you lose the flexibility of a stranded copper wire.

I think tinned stranded wire is more subject to vibration work
hardening, but much easier to work with and no chance of the wild
strand causing problems. Aircraft have all wires terminated in crimp
type connectors as far as I know. I used to build stuff that went
into the avionic bay. I ought to know, but I cannot remember how we
put the pins on the wires on those huge cannon connectors with dozens
of pins.

I thought I read in the instructions for some device – probably
either Phoenix or Traco – not to tin the ends of stranded wire, you
must use ferrules or it will be the end of life as we know it.

Or, just solder the stripped wire and not use ferrules.

The crimpers are not really needed - the terminal block does a fine
job of squashing them. Of a pair of channel locks if you must.
The ferrules are really just to keep wire strands from sticking out
and causing a short and to make reuse easier.

Oh great, now I have to think about getting some. The crimpers
alone cost a fortune!

We added some ferrules at sites...
