When building for hybrids

(sorry if someone answered this already, couldnt find anything about it) does it really matter which side you build for?

i have a glass boxer and im not entirely sure which one i want to focus on. i think in the end ill build more into boxing but is there a sort of “rule of thumb” between choosing to build into the magic or fs of a hybrid?

Generally people build more into strength when making a warlock slot, but you can go 120m/150s if you want snare
