If you are physically fit and move fairly fast for your age, and have eyesight better than 20/20 uncorrected...then stock fitting is a complete waste of money IMO.
If you have poor eyesight or wear glasses and/or contacts and can't move too fast, then it may help....?....That so called perfect fit changes from summer to winter with the clothes....
This is just my opinion, others will vary for sure.
I have a lot of shotguns and none of them are fitted. I do use a removable leather slip on to protect the butt plate and or butt checkering as I set the gun down while hunting. Most were bought used, but all have LOP at or over 14.25" as I am tall with long arms.
I've seen an awful lot of men who can pick up any unfamiliar gun and shoot it accurately and consistently, so I think shooting and practicing is the most important factor with any gun.
