should I cut the fan leaves?

No you need them outdoors till later in season it protects and helps them grow big and strong later in season after stretch I usually defoliate the middle of the plant some

Fan leaves are the solar panels, do not remove!

Looks like it's initiating lateral branching on its own without removing any fan leaves or tops. You don't need a tight canopy outdoors... Not necessary and really no benefit to remove anything unless you're specifically training it to grow a certain way, ie low and bushy vs letting it go vertical.

What these others have said go with it. I only remove yellow leaf down the road. If those are autos leave them be if they are photoperiods i'd put them into a larger pot.
