Interesting topic for which there are definitely some stats nerds analytics about. Went down the rabbit hole during lunch. Most of the data are from the NBA camera analytics that chart ball and player locations dozens of times a second during every play. Allows for spatial analysis of shooting, rebound, player locations relative to the ball, height of the ball, etc. Wild stuff.
--First interesting observation:
The
average distance of rebounds doesn't really change too much for 3pt vs 2pt attempts. But there is a bit more variance for 3pt vs. 2pt. (
Do Longer Shot Attempts Mean Longer Rebounds? | Northwestern Sports Analytics Group)
A hand-calculated analysis with some neat graphics suggests slightly higher % of "long rebounds" for 3pt shots. However, note the distance breakdowns are not really "long" versus "short", in my opinion. They define ranges as 0-3', 4-6', 7-21'. That last range is pretty wide, and is considered a "long" rebound. I'd argue that 7-10' is not really a "long" rebound and is much different than 15-21%, but the authors don't go that granular with the data, unfortunately (

Be that as it may, here's the breakdown of average rebound length:

We're only really talking about 1.5-2' longer rebounds for 3's, on average.
--Second interesting observation:
The data set you use (NBA season year, specific groups of teams, etc.) and study methodology can result in significantly different conclusions about OReb% based on shot type, shot distance, etc. Need context, data details, and can't over-generalize!
For example:
OReb% was found to be highest for <8ft shots and 3pt shots vs. shots in the 12-20ft range by these nerds (from data from before 2012 season):

However, the OReb% was found to be similar for all missed shots >15ft, was highest for <10ft" from a 2015-16 NBA dataset-

To gameplan best for 3pt shooting, the team should either just (1) not do traditional "crashing" of the glass on 3pt shots, having perimeter players retreat back on D, or, (2) "soft crash" to 8-15ish ft range range, adjusting based on 3pt shot location (key, elbow, corner)
