Strength is still used for the minimum Bow rating and damage value of bow is equal to half its rating (up to a maximum rating of 14, at which point a fully Legal Bow deal the same base DV as a fully Illegal Panther XXL assault cannon). Also Attack Rating is influenced by the rating of the Bow.
Strength is added to the listed Attack Rating of melee weapons (except for Whips, where you instead add Reaction). Both Strength and Reaction is used for the Unarmed Combat's Attack Rating.
Strength is also used both as a linked attribute to Close Combat as well as one of the opposing attributes when the attacker is restraining, squeezing or tackling an opponent. And for Athletics when Climbing or Jumping or when there is extra resistance (for example running through mud, swimming against the current or breaking out from a critter using the Engulf power).
Hits from a Strength test is adding to the damage value while trying to break through a barrier with axes, picks and hammers etc.
Strength is setting the limit of how much you can lift before taking a Lift/Carry test.
The attackers Strength is used as a threshold if a defender in melee combat is trying to Wrest the attacker's melee weapon away from them as part of a Block action.
Strength (+ Body) is used to prevent you to get pulled away or things from getting pulled away from you (for example against a magician using Animate Metal spell or Levitate spell, stuck with glue spray or a critter using Binding power)
TL;DR: So while Strength is not super important one also don't want to totally ignore it. I would say that most characters should aim for a Strength of 2 (otherwise they will have to take Lift/Carry tests every time they wish to pick up items that weigh more than 10kg). Melee Characters (and Medium Machine Gun users) should probably aim for a Strength of at least 3+. Or even 5+ if they are seriously focused on melee (or Heavy Machine Guns). But the only time they should have a really high focus on Strength is if they plan on using Bows as their primary weapon.
