Only a few important points you forgot to mention.
1) Mid-boom sheeting requires larger main sheet gear as you have less
leverage compared to end-boom sheeting.
2) The forces on the main sheet are generally higher and the boom is
far more susceptible to breakage, as the outer end of the boom is
essentially unsupported and the mid-sheet mounting weakens the boom
where it is attached.
3) Prevents the use of boom roller furling gear for the mainsail.

For the cruiser racer, the mid-boom sheeting is the clear winner. It
clears the cockpit and is far more friendly to guests and young
children
