I think most people I play with would be able to adapt, or at least enough so that paired with players who tend to act with more autonomy can make up for it if that makes sense. Most issues I have seen in groups I play with is folks confused about what to do but in a way where they're unsure what spell or action to do (or how the spell or action works). Not so much them being unsure of what the objective is and how to pursue it. I believe the more free form approach of being able to say something like "I want to use my magic to conjure a spear to throw at the enemy" as opposed to things like "I cast Spiritual Weapon, can I cast a bonus action spell too? Wait, do I have to cast Spiritual Weapon every turn? I'm actually already concentrating, can I even cast this?" would work nicely in a lot of the groups I play with.

Most folks I play with are more on the drama side of the drama-math spectrum of roleplaying games. There are a couple of folks who love to really delve into options and make super well rounded min maxed characters but most just want to have a fun story. Even the ones who really enjoy the min maxing still do it in a way that fits their character.
